What does COM mean on a 2 way light switch?
Wiring a One Way Switch A one way light switch has two terminals which is a common marked as COM or C. The common is for the live wire that supplies the input voltage to the switch. The other terminal is marked as L1 and is the output to the light fixture.
How does a two way light switch work?
Two way switching means having two or more switches in different locations to control one lamp. They are wired so that operation of either switch will control the light(s).
How do you wire two switches and lights using the same power source?
If you’ve mounted two switches in the same electrical box, prepare two black wires. Connect one end of the 6-inch wire to the top terminal of the first switch. Twist the other end together with the black wire from the incoming circuit cable and the black wire from the cable going to the second switch to form a pigtail.
How do I wire two lights to different switches?
How does a 2 way light switch work?
A 2 Way Switch Wiring Diagram with Power Feed from the Switch light : The power source comes from the fixture and then connects to the power terminal. You will see that there is a hot wire that is then spliced through a switch and that then goes to the hot terminal of the light.
What kind of wire do you need for a 2 way switch?
When wiring a 2-way switch circuit, all you’re really doing is controlling the power flow (Switching off/on) to the load (a light, lamp, outlet, ceiling fan etc..). Now a typical circuit will contain a 3-wire cable known as romex. The cable consist of a black wire, a white wire and a bare copper wire.
Where is the Green screw on a 2 way switch?
The Green screw on the 2-way switch is for the ground so all ground wires should be connected as seen below. All ground wires (bare copper) are all now connected (incoming ground, load ground and switch ground). This makes for a safe protected circuit by having all grounds intact.
Where are the outlets on a light switch?
Outlet receptacles and switches in many cases are produced with push-fit wire connection slots on the back, combined with the traditional screw-terminal contacts on the sides from the device.
