how do you wire up a light switch?

Answer 1

theres only 2 wires a white and black look on the switch the screws should be color coded. there might be a ground wire also just connect it to the box

Answer 2

Household 120v wiring (I'm assuming USA) consists of Hot (black or sometimes red), Neutral (white), and Ground (bare copper or green). For obvious reasons, do this work with the circuit breaker OFF

To turn a light on, you need to connect its black wire to hot, its white wire to Neutral. The ground wire (if it has one...the bare or green one) is connected to Ground for safety. In some cases, the light will only have a green screw...your ground wire will connect to that screw.

To make the switch do its thing, you need to use it to make/break the hot wire (NEVER EVER BREAK THE NEUTRAL INSTEAD...that leaves the light hot even though it's not lit). Run your power from the breaker panel(hot, neutral, AND ground) to a junction box. Run another h/n/g to the light. If you're using household 2 conductor (with ground) NM cable (i.e. Romex, etc.) then run another length to the switch.

Wire the switch as follows: Black to one screw on the side, white to the other screw on the side, ground to the green screw on the corner.

In the junction box, wire nut together all grounds.
1) Wire nut together the neutral from the power and the neutral to the light(ONLY TWO).
2) Wire nut together the hot from the power to the black that goes to the switch.
3) Wire nut the white that comes from the switch to the black that goes to light.

This should do the trick.

Answer 3

The black wire, which is hot goes to the copper colored screw and the white wire goes to the silver which is nuetral and the bare copper wire goes to ground which is the common or ground also. the naked wire is a backup for the white or common in case the common fails.
