A single-pole switch has two brass terminal screws on the side that receive the black (“hot”) wires of the circuit. One black wire comes from the power source and the other goes to the light(s).

Where does the white wire go on a single pole switch?

The white (neutral) wire connects to the silver screw, or you place it in the back wire hole on the same side of the device as the silver screw. The black (hot) wire goes to the brass screw or into the hole in the back of the device on the same side as the brass screw.

How many hot wire connections are on a single pole switch?

Light switch wiring. A single-pole switch is connected to three wires, a hot wire, a switchfoot, and a ground wire. There should be one wire for each terminal. If your switch doesnt have all three wires, its time to change them right away.

Why does a light switch have two black wires?

The bare or green-wrapped ground wires serve as a backup to divert the power safely away in case of an electrical fault. In most cases, two black wires will be attached to the switchs two terminal screws. The ground wires will be connected to each other and attached to the grounding screw on the switch.
