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. You can use a two way switch for one way switching. Just ignore the L2 terminal.
What is a double light switch called?
Double pole light switches, also known as a four-way switch, are two single pole switches put together. Two separate circuits are controlled by one switch. This is typically used to control a circuit from multiple locations in a series of three switches on one circuit.
Does the black wire go to L1 or L2?
The incoming circuit wires that provide the power are referred to as the line wires. L1 (line 1) is a red wire and L2 (line 2) is a black wire.

Does it matter which wire goes where on 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.

Is L2 live or neutral?
L1 is live and L2 is neutral.
Which wire goes to L1 L2 com in a switch?
The yellow wire goes into the common terminal, red goes into the L1 terminal and blue goes into the L2 terminal.
Where do the red and black wires go on a light switch?
Basic Knowledge of How to Wire a Light Switch Black Wire – This is the hot or load wire.White Wire – This is the neutral wire.Bare Copper (Green) Wire – This is your ground wire.Red Wire – This wire is used for 3 or 4 way switches and will connect the switches together so they can each control your lights.
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.
Does it matter where black and white wire goes on light switch?
It doesn’t matter as long as you do it the same on both switches. So, if you connect it to the upper right terminal on one switch, connect it to the upper right terminal on the other switch. Connect the second traveler wire to the terminal opposite the red wire terminal.
Does positive and negative matter on a light switch?
The circuit works the same no matter where you put the switch. Part of the electrical code (for house wiring) says that the switch should always go between the hot conductor and the load. This is for safety.
