Best Light Switch Timers Reviews and Guide


You may occasionally want a switch in your home to operate automatically. While you’re away from home, you might want to prevent burglaries. Perhaps you have a regular wake-up time and dislike stumbling around in the dark every morning. Or perhaps you simply prefer the comfort of lights during times when you know you’ll be at home. Whatever your motivations, one solution to this issue is the use of an automated light switch timer. So, we have compiled a list of the best light switch timers in this article.

Three of the best models money can buy will be thoroughly examined for you. But first, here is a brief summary of your choices and some considerations for your decision-making.

Different Light Switch Timer Types

Mechanical timers are probably something you remember from the dark, prehistoric decade of the 1990s when dinosaurs still roamed the planet.

These were timers that could be used to power a variety of appliances by plugging them into an electrical socket. Since they could be used to turn a few lamps on and off while you were away, they were especially well-liked by regular travelers. They typically operated by placing groups of pins into a rotating dial. The pins would turn the switch on and off as the dial turned.

In a similar vein, mechanical bathroom timers are nothing new. The switch will activate when a dial is turned, usually for five to one hundred minutes. They are frequently used in hotels to operate infrared lighting and bathroom fans. There aren’t many more practical uses for them, though.

Simply said, digital timer switches represent this technology’s next step in development. They take the place of a wall light switch in a manner similar to a mechanical bathroom timer. They also provide you the option to plan the on and off times of your lights, much like a mechanical plug-in timer.

A mechanical timer, however, has several restrictions. You can only set one schedule using a single 24-hour dial. You can typically set a different schedule for weekends or even a seven-day schedule with an automated light switch. Today, we’re going to be looking at this kind of switch.

Factors to Consider

Let’s discuss features now that we are aware of what we are looking at. You must first determine how many watts your circuit needs.
You probably won’t run into any issues if your switch only operates one ceiling light. For a full room, many people, however, employ automated light switch timers. Even circuits that manage a line of kitchen appliances can use them.

If you wish to turn off those outlets at night to conserve phantom power, this is helpful. However, under these higher-wattage circumstances, you should double-check your features.

Considering the kinds of lights or appliances you’re powering is another crucial step. An outdated incandescent bulb can be powered by any switch. LED and CFL lights, however, have distinct specifications.

Additionally, you should be aware that the majority of switches do not accept dimmers. In addition, some light switch timers are inappropriate for use with motors. This is due to the “peak wattage” that electric motors have, which occurs when they are turned on. The typical wattage may be handled perfectly by a switch. It must nevertheless be able to handle the peak wattage.

Remember that not all lighting circuits are created equal. Three-way circuits, for instance, have switches at both ends of the room. There are also four-way circuits, in which the same light is controlled by three switches. However, not all automated light switches support multi-way circuits. All automated light switches will operate on a typical single-switch circuit.

A light switch timer, as the name suggests, essentially combines a timer and a light switch. In order to automate the use of the various lights in your home, you can connect timers to them.

But before getting one, check out these factors below:

Number of Switches:

Even though you can easily purchase numerous light switch timers for various lights throughout your house, many of them come in packs of two switches. These two-switch timer packs typically provide the user with a better value for their money while enabling you to power numerous lights simultaneously.


You must make sure that whatever switch you purchase can manage the power requirements of your light bulbs. Thankfully, even if you want to use these light switch timers to power household appliances, it shouldn’t be a problem as the majority of them have a maximum wattage rating of roughly 1800.


Your light switch timers should be dependable in addition to being able to manage large power loads so that they last for a long time and do not interfere with your light bulbs. Thankfully, most of them offer a 1-year warranty, and a few of them even have a 5-year warranty.

Even though these characteristics and factors are some of the most significant ones, there are still other things you need to be aware of.

As a result, in addition to listing different switch timers along with their features and specifications, we have also provided a “Buying Guide” for the top light switch timers.

How to Install a Light Switch Timer Safely

Light switch timers should be fitted in accordance with the manufacturer’s published instructions and installation diagrams.
If you have any concerns regarding safety or are unclear about the proper installation techniques, it is best to get in touch with a professional electrician.
It is anticipated that the installation will be finished in around 15 minutes.

The following steps should be taken during the installation process:

Step One: Turn the Power Off

Turn off the power at the circuit breaker to start the installation.
To make sure that no power is generated, a voltage tester should be employed.

Step Two: Identify the Live Wire

Reset the circuit breaker, then locate the live wire with the tester.
Before marking the live wire with electrical tape, turn off the power once more.

Step Three: Split the Wire Ends

Make sure the wire ends are kept apart so they don’t touch the switch box or other objects.

Step Four: Connect the Wiring

The electrical wiring should be connected using a terminal block.
The amount of space and number of wires needed for the connection will determine the best type of terminal block.
To power the light switch, the block must also be able to conduct the maximum amount of current.
Testing will be necessary to make sure there is no overheating and the wires are still firmly in place.

Step Five: Arrange the Wires

Gather the wires with care, then tuck them into the switch box.
The timer switch should then be firmly fixed to the mounting before the cover plate is secured once more.
Now it’s possible to turn on the circuit power once more.

How to Program a Light Switch Timer

There are various types of light switch timers, and each one requires a unique programming procedure.
As was said before, you should adhere to the manufacturer’s recommendations and get advice from an electrician if you have any questions.
It’s crucial to check that the illumination is working properly and that the switch timer is firmly fixed.

On and T are the two modes available on manual timers (Timer).
The power will bypass the timer and the lighting will function properly if you select the “on” setting.
To have the lighting change automatically at different times, you must use the T setting.

It is recommended to program the manual light switch timer as follows:

Step One: Identify the Dial

Find the dial with the pointer on the main section of the switch.

Step Two: Adjust the Tabs

To set the times you want light, align the pointer properly and push down the tabs.
The lighting won’t be on during those times, so the remaining tabs should all be open.

Step Three: Test

Test the manual switch timer, then make any necessary modifications.

A digital switch timer works in a manner that is very similar to the manual variety. Applying the labeled buttons will ensure that the lighting is at the proper levels throughout the day. Such equipment should be used in accordance with any provided instructions.

In many situations, you might want the lights in your house to switch on automatically in a particular location at a particular time. This can include lights for your aquarium, nightstand lamps, outdoor lighting for the front or back yards, planter box lighting, and many other things.

All of these switch models have been listed together with pertinent details like features and specifications in order to make this listicle extremely informative. And now, going one step further, here is our in-depth buyer’s guide to the top light switch timers:

Number of Light Switch Timers

The quantity of switches included in the box is one of the most fundamental yet crucial considerations when purchasing light switch timers.
In general, you’ll discover that the majority of them merely include a single light switch timer.

Fortunately, if you want to use a switch timer to power various lights in your home, you can easily purchase more switches. A couple of them do, however, also come in sets of two switch timers. You typically receive a greater value for your money when purchasing such packs of light switches, which is always a plus.


The wattage rating of a certain light switch timer is one of the most important criteria that determine how well it works. As implied by the name, this rating merely informs you of the maximum power load that a switch is capable of handling.

It’s crucial to consider whether you want to add a timer to one of your home appliances or power several high-watt bulbs with a single switch.
The average wattage rating of light switch timers is roughly 1800 watts, which is significantly more than you will ever need for light bulbs.


Even though this has no impact on how well a light switch timer performs, it is still crucial to make sure you purchase a dependable light switch timer.
This is to guarantee that whatever product you purchase will last for a long time before you need to replace it.

Almost the majority of the light switch timers covered in this article come with a one-year warranty. Having said that, there are also possibilities for warranties of up to five years.


What are the Best Light Switch Timers to Buy?

There are many different light switch timers available that are perfect for various uses. You can program each of these timers to turn on and off the illumination at specific times, creating the impression that someone is on your property and discouraging trespassers. They work with single, double, or triple switches and the entire range of light bulbs. You should be careful to choose a light switch timer that will work for your needs and be simple to install.

Do LED Lights Work with Timers?

LEDs and energy-efficient lamps can be used with timers without any issues. However, if the right installation techniques aren’t used, there can be some flickering or continuous lights. This is due to the fact that these lights lack a resistance feature because they are inductive.
The inductive element is continuously charged and drained as a result, causing the timer to cycle on and off. The switch timer’s modest current output is also adequate to maintain the LEDs’ low brightness. Due to the timer switch fuse blowing simultaneously with the light bulb as a result, it is necessary to turn off the mains before changing a fuse.

The problems of using LED lights can be solved in a variety of ways. It may be possible to insert a sizable external resistor between the switch and the light bulb to enable the operation of 20w lights. Increasing the number of bulbs is another option to meet the timer switch’s minimum load requirements. Additionally, it is suggested to power LED lights with digital timers.

How Do I Know Which Wire is Neutral When Installing My Switch?

For a light timer to continue receiving power and perform as intended, a neutral wire must be connected. This wire enables load control, accurate timekeeping, and remote communication.

Two white neutral wires should be visible in the electrical lighting box. These wires could be fastened with a wire fastener and linked together.
Such neutral wiring won’t necessarily be present, though. To locate the neutral wiring, a flathead screwdriver, a Phillips screwdriver, and a handheld voltage tester will be needed.

How Does a Light Timer Work?

The light timer is a clock-integrated electrical circuit. According to each person’s needs, it can be set to turn the lighting on or off at particular times. Devices with one or more electrical outlets, as well as those integrated into a full security system, are available for purchase. Both mechanical and digital timers come in a huge variety.

Electrical circuits powered by the main suppliers are commonly coupled to digital timer switches. They lack moving parts and have switching and timing electronics. These switches can turn on or off lights at predetermined times. The pre-setting and cyclical arrangement of lighting levels is possible with some of these switches.


You can save a tonne of time and electricity by using a device like a light switch timer. You can easily automate any light in your home or office that you want to turn on for a predetermined amount of time each day by using one of the top light switch timers mentioned earlier in this article.

The Dewenwils offers a very high wattage rating of 1875 watts when it comes to the wattage rating of light switch timers. Additionally, you receive two light switch timers in total, which is more than most other products on the market. With this one, you receive a standard warranty of one year.

However, the Leviton VPT24-1PZ can be a fantastic option if you’re looking for a light switch timer that is incredibly dependable and has a warranty. The only option listed above that comes with a 5-year warranty is this one. This one offers the purchaser an additional wattage rating of 1800 watts, making it perfect for heavy-duty use.
