Buying Guide
How many types of the light switch timer are there?

How can choose the right light timer switch for my home?
Because there are different types of programmable light switches, you need to be sure what kind of timer switch would be ideal for you. First of all, before buying anything you must look for the wattage ratings. Add the wattage of all the bulbs or motors you want to control with your device and then find the right option.

Timer switches can also enhance the safety of your home as they give an appearance that someone is at home, turning the lights on and off automatically. There are both indoor and outdoor light timer switches available.
Should I look for a timer switch that runs on battery or alternating current?
It ultimately depends upon which type you prefer. The timer switches that come with built-in battery work well, but if the battery falters then, the whole device becomes useless.

How to set a timer switch for lights?
It is not that difficult at all. Just turn off the main power from the circuit breaker or unscrew the fuse which controls the fixture and the wall switch. Then remove the cover plate of the switch and use a tester to confirm that the power is off. After that unscrew the existing switch and pull it out but let the wires attached. Now compare the wires with your new switch using the manual that comes with it and then connect them to the old wires and then fix the timer switch and turn on the power. Now you are all set to program your timer switch as per your requirement.
How does a timer switch work?
Timing mechanism controls the timer switch, and the switch is connected to an electric circuit that is operating from the central power. You can select a setting on the timer and find the button that enables you to toggle between the automatic settings and the timer. Locate the outlet that you want your timer switch to work on and plug it in. After that just set the timer and you are ready to go. Note that the timer is specifically for your lights, and other electronic devices such as your USB wall outlets and GFCI outlets will work as usual.
