About me:
There are three basic types of light switches used in the home: The single-pole switch is used when one or more lights are to be controlled from a single location. The 3-way switch is used in pairs when one or more lights are to be controlled from two locations. The 4-way switch is used in combinations with two 3-way switches when one or more lights are to be controlled from three or more locations. The terminology used with these switches may sound daunting but the actual wiring is straight-forward and simple. Turn off the circuit breaker supplying power to the switch circuit that you will be working on.

A single-pole switch has two brass screw terminals. Both are hot leads for one incoming and one outgoing line. Those are all the wires that connect to the switch. The neutral wires tie together separately and the ground wires tie together separately in the box. Many new switches include a ground screw; others may not have one. If you have the choice, how do you hook up an electrical switch a switch with a ground screw terminal. That's where the bare copper or green wire connects.

Power to the switch. Pow er from the lights. First of all we should connect the ground wires to the box. If the light switch has a ground screw on it usually green and at the bottom of the switch , connect it now.

The hot wire in a volt residential AC circuit usually is coated with black insulation, while the return, or neutral, wire is white. A single-pole, single-throw switch — such as a light switch — works by interrupting the hot wire, so it has two brass terminals for the hot connections and no silver terminals for neutral. Hooking up a switch is the essence of simplicity. You connect the black wires in the electrical box to the switch terminals, and the white wires to each other. The switch also has a green terminal for the ground wires, which usually are bare. Turn off the power to the circuit before you begin wiring the switch. Find the breaker in the main panel that controls the circuit and turn it off.

In general, a light switch breaks the hot wire lead when it is off and connects the hot wire lead when it is on. The neutral lead and the ground lead are never broken that is, they are connected, either continuously, or through a permanent attchment, such as a wire nut. Power source through switch box - When power comes through a box containing a light switch and continues on to the light, the switch is attached on one terminal to the black or sometimes red line from the power source and on the other terminal to the black or red line going on to the light.
