Can a circuit have 2 switches?
A two way lighting circuit enables one circuit to be turned on or off by either of two switches. The circuit may have one or more lights in it. This type of circuit uses two of the two way switches. A wiring diagram and a circuit diagram are shown below.
What does L1 l2 and COM mean?
The single direction plane switch has two L1 terminals, the terminal to which the neutral cable is connected – the blue cable (traditional black, before changing). COM or Common is the terminal to which the live core cable is connected – this is the brown cable (red era).
What is the difference between 2 way and 3-way switch?
A two-way switch turns lights on or off from one location only. Light can be turned on or off from 2 locations with a three-way switch.
When should you use a 3 way switch?
A 3-way switch is one that allows you to control a ceiling light (or other electrical fixture) from two separate locations. Common scenarios would be 3-way switches located at both the top and bottom of a stairway, or having 3-way switches next to doors in a room with two entry points.
What happens if I wire a light switch backwards?
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 black or red go to L1?
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).
What Colour wire goes to 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. Together, they show the motor voltage.
