What is L1 L2 and com?

What is L1 L2 and com?

L1 and L2 are “line 1” and “line 2,” and “COM” is “common.” Depending on the position of the switch, either L1 or L2 is connected to “common”—hence the name; it is the terminal that is “in common” between the two positions.

What is L1 and L2 in a switch?

A one way switch has a common (C) and Line out (L1) terminal. A two way switch (for switching a light from two different locations like in a hallway) has a common (C) a L1 and an L2 terminal. L1 is off when L2 is on and vice versa depending on the switch position.

Where does red wire go on single pole switch?

The red wire will go on one of the brass screws, but whether it goes on the left or the right depends on how the room is wired. If you don’t know how it was, connect the red wire to one of them, turn the power back on, and try the lights. If the switches malfunction, switch the lower wires on the new switch.

Does it matter which wire goes where on a light switch?

Assuming this is the case, yeah, it does not matter which you connect to hot and neutral. It depends on the sort of switch. In the US, Canada, and Mexico, simple switches called “single pole” have two screw terminals of the same color. You can attach either wire to either terminal, and it will work correctly.

How do you make a one way two way switch?

To replace two switches with one, simply eliminate one switch from the “power” circuit, and connect both outgoing wires (one is red, one is black in your photo) to the same switch. Beware: some switches are “3-way”, and so while they may appear to have separate terminals, the reality is they don’t.

Do you need special wiring for a dimmer switch?

New dimmers have either a green grounding wire or a green ground screw that you’ll have to connect to a grounding source if one is available. Houses wired with plastic-sheathed cable almost always have bare copper ground wires that you’ll connect to the toggle dimmer switch.

Does red wire go on top or bottom of 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.

How do you hook up a dimmer switch to a circuit?

If your dimmer doesn’t have terminal wires, place a hook at the end of the stripped wire, wrap around the screw, and then tighten the screw. Attaching the dimmer switch to the circuit wires extending from the box is fairly straightforward since it usually involves just two hot circuit wires attaching to two hot wire leads on the switch.

What are the ground wires on a dimmer switch?

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. on installing and wiring a Dimmer Switch.
