The following is the simple schematic of a three-wire 2-Way Switch wiring. The first way of wiring uses a couple of Two-Way Light Switches with a three wire control (3 Wire Control). Let us take a look at both these wirings. One is an older method, which is not often used now-a-days and the other is a more modern and safer version, which is being implemented in industrial as well as residential applications. There are a couple of ways in which you can make a two-way switch connection.
The following image shows the front and back view of a typical household two-way switch.Īs I have already mentioned in the introduction paragraph, a two way switch is very useful in staircase lighting as you can turn on the light just before you start to climb the stairs and once you reach upstairs, you can turn off the light simply by toggling the switch placed near the top of the staircase. This is in contrast to a regular two terminal switch, which is just a make or break device. This type of connection is typically called a “Break before make” design, as the first connection has to be broken before making the second connection. In one position, the COM and L1 terminals are connected, while in the second position, the COM and L2 terminals are connected. The three terminals are usually named COM, L1 and L2, but sometimes the terms COM, 1 Way and 2 Way are also used. It is a standard single pole double throw switch with three terminals. So, before proceeding to learn about the wiring of a 2 way switch, we will learn about the Two-Way Light Switch, which is the main element of the 2 Way Switching, irrespective of the type of wiring used. But there is a special switch called ‘Two Way Switch’, which is the an important component in the implementation of Staircase Lighting. They essentially ‘make’ or ‘break’ the circuit.Īll the switches we use regularly to turn on or off lights, fans, etc. All the switches perform simple task of either interrupting the flow of electric current or divert the flow of current. There are different types of switches: Toggle Switch, Momentary Switch, Rocker Switch, Digital Switch, etc. A Switch is an electrical device which is used to open or close an electric circuit. The gadgets we use daily (mobile phone and laptop) consists of several switches. We use switches all the time in our homes, offices, cars, industries and many other places.
