Unbelievable Wiring A Two Way Switch For One Way Lighting

The electricity flows from the hot wire black through the 2 way switch shown in off position and then to the light and returns through the neutral wire white.

Wiring a two way switch for one way lighting. This is very useful in a number places particularly hallways and stairs. Pin1 pin2 of the first switch are connected with the pin1 pin2 of the second switch respectively. The three terminals are usually named com l1 and l2 but sometimes com 1 way and 2 way are also used.

If you are going to install a new one then go for three wire control methods. This method can be dangerous if the neutral from the ceiling rose is connected to an alternate junction box on a different circuit. A two way switch has 3 terminals.

A common c l1 and l2. The l2 terminal is unused. It is a standard single pole switch with three terminals.

As you see in the 2 way switch diagram below you will find that the phase live is connected with the common of the first 2 way switch. Before proceeding an important component called a two way light switch is the main element of the 2 way switching irrespective of the type of wiring used. Let s assume the load you are controlling is a light.

A two way light switch can also be used in in place of a one way light switch in this instance the red wire from the feed cable is connected to the common c terminal and the red wire going to the light is connected to the l1 terminal. Two way switching with power feed to the switch. By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load.

Two way switching allows you to control a light from two locations. Live connected to downstairs circuit and neutral connected to upstairs circuit. Wiring a two way switch.
