where are single pole switches used
Light switches can be used hundreds of times a year in a home. This constant use can loosen wire connections and eventually wear out the moving parts. Wiring a switch is an easy do it yourself project. Just make sure to turn off the power to the circuit you are working on. A single-pole switch is used to control lights from only one location. The switch has two screw terminals on the body of the switch. Most switches will also have a green grounding screw. A single-pole switch will have ON and OFF marked on the lever. A switch is just a break in the hot wire controlling a light.
