There are two methods of making 2 way switching connection one is 2 wire control and another is 3 wire control. When i say 2 way swithces i mean a switch with two copper screws.
Wiring Diagram For 2 Gang 1 Way Light Switch
Two way light switch wiring. The source neutral wire is spliced to the neutral on the receptacle half of the combo device and to the white cable wire running to the light. 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. This method is commonly used nowadays as it is efficient than the two wire control system. Also known as three way switching the job calls for a pair of special three way switches and an appropriate length of 14 3 conductor cable to join the switches together. This is a completed circuit. This cable contains three wires and a ground.
Lets assume the load you are controlling is a light. According to the schematic diagram of 2 way switch circuit above the common of both the switches are are connected with each other. 2 way switch wiring using three wire control. 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. Red black white and bare. The power source comes from the fixture and then connects to the power terminal.
For the span between the first and second switch boxes run 3 wire romex. 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. 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. At the light it connects to the neutral terminal. A light fixture can operate with two switches in different locations.
A 2 way switch wiring diagram with power feed from the switch light. Between the lightbox and the first switch box there should be a length of 2 wire a black white and bare wire inside. Wiring two switches to one light fixture adds convenience to any room with two entryways. You will see that there is a hot wire that is then spliced through a switch and that then goes to the hot terminal of the light. Two wire cable runs from the combo to the light fixture and the switch output is connected to the black wire running to the fixture hot terminal. Use two 2 way switches to create a two way switch system.
By wiring a 2 way switch the circuit below shows the basic concept of electricity flow to the load. It is also a new method to make a 2 way switching connection as it is a little different from the two wire control method.
