What is L1 and L2 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.
Does it matter which wire goes where on a light switch?
The white (neutral) wire connects to the silver screw, or you place it in the back wire hole on the same side of the device as the silver screw. The black (hot) wire goes to the brass screw or into the hole in the back of the device on the same side as the brass screw.
What happens if you wire a light switch backwards?
The fixture still works if you reverse the wires, but the socket sleeve will be hot, and anyone who touches it while changing a bulb can get a shock. When wired correctly, the socket sleeve is neutral and only the small metal tab at the base of the socket is hot.
Does the black wire go to L1 or L2?
This is the most common type of switch, and is used where a light is controlled from a single switch. The Yellow wire goes in the common terminal, Red in the L1 terminal and Blue goes in the L2 terminal. The Grey wire goes in the common terminal, Brown in the L1 terminal and Black goes in the L2 terminal.
How do you hook up two lights to one switch?
You can do this light switch wiring in one of two ways. The most common is to daisy-chain the light fixtures by connecting them to each other and hooking the first one up to the switch. The other way to wire multiple lights to one switch is to connect all of them directly to the switch in a “home run” configuration.
Can you wire a light switch wrong?
If a light switch is wired up wrongly, a short circuit may takes place if you give phase and neutral to the switch terminals. Always connect neutral wire to the one terminal of the light and phase to the one terminal of the switch and off wire to the other terminal of the switch to the light other terminal.
Where does red wire go light switch?
Attach the red wire from the light fixture to the nut at the top left of the switch. Connect the bare copper wire to the green nut at the bottom left of the switch. Push both switches into their boxes and secure them with screws at top and bottom. Turn on your power and test the switches.
Why is there a red wire in my light switch?
The exact purpose of a red wire for a light fixture can vary. Except in rare cases, it is a hot wire or a switched hot wire. If turning the switch off turns the wire off, the red wire delivers power from the light switch. Note: Never touch wires or their connection points while the circuit is energized.
Why are there 2 black wires on light switch?
If the light turns on, the second black wire you connected to the switch is the switch feed and the unconnected black wire is the feed to the other loads. If the light doesn’t turn on, then it’s the other way around: the connected wire feeds the other loads and the disconnected wire is the light feed.
Can I connect red and black wires together?
If the red and black wires are connected together already and energized, yes you can do that but you will need a pull chain light or a remote control, if they are not switch controlled.
What happens if you don’t ground a light switch?
If the light switch has a screw for a bare ground wire but your electrical box doesn’t have one, you can leave that screw empty and connect your other wires to the hot screws. Even if you don’t have a ground wire, the metal box may be grounded even if you don’t have one.
