There are two methods of making 2 way switching connection one is 2 wire control and another is 3 wire control. Logically it cant be done as both switches would need to be on for the circuit to work power the bulb that is but a two way switch system means that either switch should be able to turn on the bulb.
Two Way Light Switching Explained
Wiring a two way switch. We look at the eu colour coding wires. 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. This can be confusing. The following is the simple schematic of a three wire 2 way switch wiring. Two way switch can be operated from any of the switch independently means whatever be the position of other switch onoff you can control the light with other switch. By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load.
How to wire a two way electrical switch step 1 safety first. Sometimes referred to as a single pole single throw switch abbreviated to spst. When i say 2 way swithces i mean a switch with two copper screws. Step 2 identify the electrical wires. 2 way switch single pole single throw or spst a simple on off switch. Lets assume the load you are controlling is a light.
You can observe in the schematic that both the com terminals are connected together. Can i wire a 2 way switch to existing intermediate wiring. If you look inside an existing wired in two way switch you will see quite a few wires of differing colours. Before you begin make sure that you turn the power off at the main junction box for the area you. The first way of wiring uses a couple of two way light switches with a 3 wire control. This is a completed circuit.
The l1 terminals of both the switches are connected to line or phase or live of the ac supply. One thing to remember is that the wiriing on light switches is only switching the live wires not the neutral if you see black wires or blue wires attched to the switches these are not neutrals. The two terminals are either connected together allowing current to flow or disconnected from each other breaking the circuit as you throw the switch. Go to the box where you will be installing the electrical switch. Okay thanks for your reply i might try to canabulise the switch to put 4 connections from the old switch prob wont work as springs etc will pop out just wished i could get the switch dont suppose anyone out there has got one its a newlec but i think also branded as altowickes b and q shiny black insert with a clipon surround. Step 3 wire the.
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.
