Which wire goes where on a switch?
Which wire goes where on a switch?
When you turn on a light switch, power goes to the light through the “hot” (black) wire and then back through the neutral (white) wire to the ground. The bare or green-wrapped ground wires serve as a backup to divert the power safely away in case of an electrical fault.
What does L1 and L2 mean on a light switch?
Wiring a One Way Switch The other terminal is marked as L1 and is the output to the light fixture. When you’re wiring decorative light switches such as chrome or stainless steel etc, you’ll find that the switch will also have an L2 terminal which means it’s a two way switch.
What happens if you wire a switch wrong?
But here’s the catch: If you connect the circuit wires to the wrong terminals on an outlet, the outlet will still work but the polarity will be backward. When this happens, a lamp, for example, will have its bulb socket sleeve energized rather than the little tab inside the socket.
What happens if you wire a switch backwards?
The outlet will still work if you connect the circuit wires to the wrong terminals, but the polarity will be backward. When this happens, a lamp will have its bulb sleeve energized instead of the small tab inside the sockets.
Does the black wire go to L1 or L2?
Brown for L1, Black for L2 and Grey for common.
Is L1 and L2 the same as 1 way and 2 way?
Two way switch In one position, COM and L1 are connected just as in the one way switch. In the other position, COM and L2 are connected. Note that L1 and L2 are never connected together. Again, some makes of switch may have alternative markings such as L1 L2 and L3.
Can you wire a 3 way light switch?
Take a closer look at a 3 way switch wiring diagram. Pick the diagram that is most like the scenario you are in and see if you can wire your switch! This might seem intimidating, but it does not have to be. With these diagrams below it will take the guess work out of wiring.
Where is the red wire connected to the SW2 switch?
The red wire to SW2 is connected to the hot on the bottom half of the receptacle and to the switch at the other end. In this diagram, two 3 way switches control a wall receptacle outlet that may be used to control a lamp from two entrances to a room.
Where does the White and black wire Connect on a light switch?
At the light, the white wire connects to the neutral terminal and the black wire connects to the hot terminal. Here two switches are wired in the same box to control two separate lights.
How is a light switch wired to a neutral terminal?
This circuit is wired with a 2-wire cable running from the light to the switch location. The neutral from the source is connected directly to the neutral terminal on the light and the source hot is spliced with the white loop wire. The white wire is marked black on both ends to identify it as hot. At SW1 it is connected to one of the terminals.
