# Does it matter which wire goes where on a single pole switch?

## Does it matter which wire goes where on a single pole switch?

A wall switch is a device that controls the flow of current through the live “hot” wire of an electrical circuit. 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.

### How do you wire a light switch and outlet on the same circuit?

The same three options exist when wiring separate devices. To have the switch control just the outlet, connect the hot circuit wire to one of the switch terminals, and then connect the other switch terminal to the brass terminal on the outlet with a short jumper wire.

#### How does a combination switch work?

Combination switches are always installed with through-switch wiring and never with end-line wiring. That means two or three cables enter the box. Shut off power to the circuit before removing the old switch. Your choice in combination switches was once limited to a switch and a receptacle or switch and a switch.

What wire goes to L1 and L2?

L1 (line 1) is a red wire and L2 (line 2) is a black wire. Together, they show the motor voltage. Having both an L1 and L2 indicate that the motor voltage may be 240 volts.

What is the common wire on a switch?

live wire
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.

## Does a single pole switch need a neutral?

Question; A single pole switch does not need a neutral, so why would you want a neutral in the switch box? Answer; Because changes or additions might require a neutral. Since there is no neutral in the switch box you cannot; – Install a digital timer – Install a motion sensing switch.

### What happens if you wire a switch backwards?

When an outlet is wired in reverse, the hot wire is now on the supposed neutral side. So, if you were to plug in the same lamp as noted above, the lamp socket would have power even if the switch was off since the switch is only on the hot side.

#### Can outlets and switches be on the same circuit?

Basic answer to your question of can a mixture of lights and receptacles be installed on a single circuit is yes.
