2 way lighting circuit with intermediate switch.

How to wire 2 way light switch in this video we explain how two way switching works to connect a light fitting which is controlled with two light switches. The four terminals of intermediate switch construction and its operation are shown in fig below. A 2 way switching connection means you can control an electrical equipment like bulb by two switches placed at different places generally used in the staircase. Years ago it was very common to wire lighting circuits in singles cable and by this minimising the use of copper.

The circuit consists of a two way switch at each end top and bottom switches in fig 2 and an intermediate switch in the middle. Construction working of intermediate switch. In an intermediate switch there are four terminals by which it changes the flowing of electric current from one circuit to another see fig 1 2 and also known as three way switch it has the ability to on and off the electric supply by two ways. When wiring a 2 way switch circuit all you re really doing is controlling the power flow switching off on to the load a light lamp outlet ceiling fan etc now a typical circuit will contain a 3 wire cable known as romex.

There is more than one way to do this depending of the type of cable available and on the installation requirements. Two way switch can be operated from any of the switch independently means whatever be the position of other switch on off you can control the light with other switch. The switch can be flipped only two ways up or down but the electricity can flow through the switch in 4 different ways depending on how it s connected into the circuit. Two way switching 2 wires this arrangement would typically be used in conduit and uses two wires between each switch.

Notice that the wire connected to the com terminals is looped straight through the intermediate switch using a cable connector. Black wire power or hot wire. To switch from two locations youll need 2 two way switches and wire them together in a particular way. 50ecb 1 gang 2 way light switch wiring diagram digital resources how to wire a 2 way lighting circuit in this video i show how to wire a light that can be turned on and off with two different switches.

All three switches are connected together by a three core and earth control cable. The two way and intermediate switch will look the same on the front. The most basic circuit with only two wires at the switch. However the two way has 3 terminals on the back.
