On off Switch

Single-pole switches have two terminal screws and a toggle l Most has a grounding screw that connects to the circuit's ground wire. This type of light switch controls one light fixture (or electrical outlet) from a single location. When installing, always connect two hot wires to it, not two neutrals. One terminal connects to the incoming power-source wire, while the other is used for the outgoing hot wire to the fixture. This light switch is good for small rooms that don't have many light sources
