Wiring a 3 way light switch.
Three wires between the two end switches probably using 3 core and earth cable.
This might seem intimidating but it does not have to be.
With a pair of 3 way switches either can make or break the connection that completes the circuit to the light.
The first step in any electrical project is to make sure there is no power going to the circuit you plan to be working on.
Turn the power off at circuit breaker.
Below is a simple 3 way schematic that can be applied to all three way electrical light switch connections.

Three way switching 3 wires.
This is also known as the conversion method since it is the easiest way to add a second light switch to an existing circuit.
Usually the third wire passes the middle intermediate switch but is joined in a separate terminal block.
