Ideal Single Two Way Switch

Here we have a two way switching system that utilises two single gang two way switches and a three wire control shown in the new harmonised cable colours.

Single two way switch. A 2 way switch means there is another switch controlling the same light. Notice the black wire is the only wire that we are controlling through the 2 way switch. To switch from two locations you ll need 2 two way switches and wire them together in a particular way.

A common c l1 and l2. You have an incoming hot wire black going to one screw it does not matter if you use the brass or silver screw on the side of the 2 way switch and a black wire from the other screw on the 2 way switch going to the load light ceiling fan etc. A one way switch only has two contacts while a two way switch has three.

A one way switch basically operates as a make or break switch. Wiring a two way switch. This is the preferred approach.

If a light switch is 1 way this means it is just an on off switch. When you want to make a connection with one terminal. One of the terminals can be connected to either of the remaining two but not both at the same time.

Two way switching allows you to control a light from two locations. The single switch controls a single light or lighting circuit. The white wires are wire nutted together so they can continue the circuit.

All you need t. This arrangement is often found in stairways with one switch upstairs and one switch downstairs or in long hallways with a switch at either end. When it is turned on the two terminals are connected and when it is turned off the contact between the two is broken.
