# Question: How do you hook a 2 way light switch up?

Contents

## What wires go where on a 2 way light switch?

These two wires are the Permanent live and switched live. The Yellow wire goes in the common terminal, Red in the L1 terminal and Blue goes in the L2 terminal. The Grey wire goes in the common terminal, Brown in the L1 terminal and Black goes in the L2 terminal.

## What are the terminals on a 2 way switch?

A Two Way light switch is a simple single pole changeover switch with three terminals. These are typically labelled COM, L1, and L2 (Some may label the L1 and L2 positions as 1 Way and 2 Way).

## How does a 2 way light switch work?

Two way light switching works by having two wires in between the two different switches. What these two wires do is that they act as an alternate bridge point between the switches that allow them to connect the circuit to the light source from either switch.

## Whats the difference between a 2 way and 3 way light switch?

2 Way Switches have 3 screws, whereas 3 Way Switches have 4 screws. But irrespective of that, in both cases, you can employ 2 switches to control the load. You need to use 2-wired cable both between the switches and between the light fitting and a switch for 2 Way Switching.

## What is the difference between a one way switch and a two-way switch?

The one-way switch has two contacts and the two-way switch has three contacts. In a two-way switch, there are two, one-way switches combined in one. One of the terminals can be connected to either of the two, but not both at the same time.

## How can you tell if a switch is two way?

If the switch is down, then terminals 2 and 3 are connected. You can see (if you trace through the wires and the switches) that in the previous figure, the light is off. You can also see that if you flip either switch, the light will turn on.

## Can I use a two way light switch as a one way?

A two way switch can be used as a one way switch or a two way switch. They are often used as both.

## Does it matter if you wire a light switch backwards?

This makes things like lamps and many appliances more safe to operate. But heres 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. If these connections are backward, the polarity is wrong.

## What is the difference between a 2 way switch and a 3-way switch?

Both 2 Way and 3 Way switches are SPDT switches. But 3 Way switches have an extra pin called Grounding pin, which is not present on 2-way switches. 2 Way Switches have 3 screws, whereas 3 Way Switches have 4 screws. But irrespective of that, in both cases, you can employ 2 switches to control the load.

## Can I use a 3-way switch as a regular switch?

Yes it can work. 3-way switches are spdt (single pole double throw) with 3 screw terminals, and regular switches are spst (single pole single throw) with 2 screw terminals. Just pick the correct two contacts and you are good to go. .

## Whats the difference between a two way switch in a 3 way switch?

2 Way Switches have 3 screws, whereas 3 Way Switches have 4 screws. But irrespective of that, in both cases, you can employ 2 switches to control the load. You need to use 2-wired cable both between the switches and between the light fitting and a switch for 2 Way Switching.

## What is the difference between a 2 way and a 3 way light switch?

The 2 way switch or single pole double throw switch is a three terminal switch. Here 1 terminal is the input and the other two are used as outputs. Because it uses two switches and one appliance. In 3 way switches you use two control a single appliance from two different locations.
