What is COM L1 and L2 on a light switch?

Two way switches have a COM terminal as well as L1 and L2 terminals. When L1 is off L2 would be on. When L1 is on L2 would be off.

Is L the same as COM on a light switch?

oh yeah , er the L terminal on your new switch is the same as the common on the old switch , place wire link between the 2 L’s. and stand back when you switch on.

How do I change a single light switch to a dual?

Quote from the video:
Quote from Youtube video: Space on the wall. So i cover the hole. Make sure it's nice and level and then i want to draw the rest of the box. Over my tape. This is going to give me an outline of where to cut the new box.

What wire goes to L1 and L2?

The yellow wire goes into the common terminal, red goes into the L1 terminal and blue goes into the L2 terminal. The grey wire goes in the common terminal, the brown wire goes in the L1 terminal and the black wire goes in the L2 terminal.

What happens if you wire a light 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.

Can I use a 2 way light switch as a 1 way?

A two way switch can be used as a one way switch or a two way switch. They are often used as both. In fact many electrical retailers (including Socket Store) don’t sell one way switches as the price difference is insignificant and the two way will do the job for both.

Is L1 or L2 neutral?

When wiring a new motor, you want your “hot” wire on L1 and neutral on L2. If you operate the dial you will see 115 volts instead of 230.

Does it matter which way you wire a light switch?

In the case of a single-pole switch, these wires are interchangeable—it doesn’t make any difference which wire is attached to which screw terminal. Inside the switch is a metal pathway that closes when the switch is in the ON position and opens to interrupt the flow of power when the switch is turned OFF.

What is the L1 and L2?

L1 and L2 are levels of cache memory in a computer. If the computer processor can find the data it needs for its next operation in cache memory, it will save time compared to having to get it from random access memory.

What wire goes in the COM on a switch?

The faceplate of a single, one-way switch has two terminals: “L1” is the terminal to which the neutral core wire is attached – the blue wire (traditionally black, before the change). “COM” or “Common” is the terminal to which the live core wire is attached – this is the brown wire (formerly red).

How do you change a light switch with two wires?

Quote from the video:
Quote from Youtube video: This green screw is holding down the ground wire which is that exposed copper wire. With that loosened I unhook it and remove.

Why is there two black wires in light switch?

Black means hot, white signifies neutral, and green indicates ground. However, if you need to rewire a light switch or a plug socket, you may occasionally come across two black wires. It’s essential that you determine which black wire is hot before proceeding.

How do you replace a switch with two black wires?

Connect the top screw to the wire that feeds to the light. Connect the bottom screw to the hot wire. When you turn the power back on, and if you want to swap the direction of the switch (as in press down to turn off, or turn on), turn off the power and switch the two black wires.

Which wire is hot if both are black?

Here’s a rundown of electrical wires: The black wire is the “hot” wire, it carries the electricity from the breaker panel into the switch or light source. The white wire is the “neutral” wire, it takes any unused electricity and current and sends it back to the breaker panel.

Can a light switch have 2 black wires?

You should see two black wires, each connecting to a different screw on the side of the switch. These are called terminal screws. You will also see two white (neutral) wires that connect to one another in the box. The connection should be covered with a wire nut.

Where do you connect the black wire on a light switch?

Quote from the video:
Quote from Youtube video: The the black with the black wire on the light fixture. And the neutral to the neutral white wire on the light fixture as well. Okay it's really that simple now when it comes to ground.

What happens if you mix up hot and neutral wires?

This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it’s usually an easy repair. Any $5 electrical tester will alert you to this condition, assuming you have a properly grounded three-prong outlet.
