How do you connect a single pole switch with incoming and outgoing cables?

The correct approach to connecting a single pole switch involves understanding the function of the switch and the roles of the wires involved. In a typical setup, you will have an incoming cable providing power, which consists of a black (hot) wire and a white (neutral) wire, and an outgoing cable that sends power to the fixture or device.

By connecting the two black wires to the two terminals of the switch, you allow the switch to control the flow of electricity. One black wire carries the incoming power to the switch, and the other black wire sends the switched power to the device when the switch is in the "on" position. This ensures that the switch properly opens and closes the circuit, enabling or disabling power to the fixture.

The white wires, which are neutral, should be connected together using a wire nut, as they do not connect to the switch itself. The ground wires, if present, should also be connected to a grounding terminal or wire to ensure safety, but that is not typically mentioned in the context of connecting the switch. Thus, the method described in the selected correct answer not only aligns with standard wiring practices but also guarantees the safe and effective operation of the switch in controlling the electrical device.
