Light switches are normally located conveniently on the walls to turn power on and off to the fixtures. Some switches are equipped with dimmers, that can be used to lower or raise the output level of the light fixtures.
Light switches can be wired in special ways so that some lights can be turned on and off from more than one location, which can be extremely handy. These types of switches are known as three-way’s. Switches can come in a wide variety of styles and colors.
Switches that detect motion or light levels can be used to control lighting circuits. Air switches are also available to remotely control appliances from locations where it is impossible to have normal wiring. A common example would be the button switches for disposers that are located on countertops. Another application for air switches would be to turn on hot tub or bathtub jets. Plunger switches are used to automatically turn closet lights on when a door is opened.
- 1x per year: Check each switch and the cover plate surrounding the switch. The cover plate can break and need to be replaced, or the screws may come loose and need tightening. Caution: do not overtighten the screws as that can crack the cover plate also! There is nothing inside the actual switch that can safely be maintained or repaired. If a switch begins to operate poorly, stops working entirely or feels warn to the touch it should be reported to a licensed electrician and replaced immediately.
