Unbelievable 3 Wire To 2 Wire Light Switch
Therefore the 2 switches the light 3 way.
3 wire to 2 wire light switch. There will be an additional wire needed often red to connect the switches together to a dedicated screw or input on the switch that is specifically marked for this purpose. Connecting a two wire light fixture to a three wire power supply cable is not an ordinary occurrence. Com on the first switch connects to com on the second switch l1 on the first switch connects to l1 on the second and l2 on the first switch connects to l2 on the second.
You can observe in the schematic that both the com terminals are connected together. One example of a 3 wire lighting system. Cable d fig 2 is a three core and earth this is the 3 wire control that links the two light switches together.
The following is the simple schematic of a three wire 2 way switch wiring. Enjoy the videos and music you love upload original content and share it all with friends family and the world on youtube. Change the 2 wire without neutral wire installation to 3 wire with neutral wire installation it s the last option we would recommend to change the bulb instead of changing the wiring.
This diagram illustrates wiring for one switch to control 2 or more lights. The l1 terminals of both the switches are connected to line or phase or live of the ac supply. The 3 wire system is less common than the 2 wire system it includes a neutral at the switch as well as the live and switched live wires.
You can do the work with the proper tools materials and electrical circuit knowledge. This video explains how the two switch two light circuit works. The source is at sw1 and 2 wire cable runs from there to the fixtures.
The hot and neutral terminals on each fixture are spliced with a pigtail to the circuit wires which then continue on to the next light. The first way of wiring uses a couple of two way light switches with a 3 wire control. 3 way light switching new cable colours 3 way light switch old cable colours 3 way light switch using a two wire control.
