This video explains how the two switch two light circuit works. This is the simplest arrangement for more than one light on a.
You can do the work with the proper tools materials and electrical circuit knowledge.
3 wire to 2 wire light switch.
One 2 core earth cable takes live and neutral to the switch back box a second cable takes the neutral and switched live to the light. The l1 terminals of both the switches are connected to line or phase or live of the ac supply. The source is at sw1 and 2 wire cable runs from there to the fixtures. 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. 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.
The lighting could be added to the three wire cable provided that the circuit breaker is no more than 15 amps and the wire size is no greater than 14 gauge.

Moreover for our upcoming version together with the bluetooth 5 0 mesh launch in late 2018 we are targeting to support 80 or above led bulbs with 1w or above and it s believed that this is the. Connecting a two wire light fixture to a three wire power supply cable is not an ordinary occurrence. Cable d fig 2 is a three core and earth this is the 3 wire control that links the two light switches together. An example of a 3 wire lighting circuit is shown in figure 2.
One example of a 3 wire lighting system. 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 following is the simple schematic of a three wire 2 way switch wiring. 3 way light switching new cable colours 3 way light switch old cable colours 3 way light switch using a two wire control. Therefore the 2 switches the light 3 way. 2 way light switch 3 wire system new harmonised cable colours 2 way switch 3 wire system old cable colours 2 way switch two wire control three way switching.
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. 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. A three way light switch is one where you have two switches that have the ability to control the same light or set of lights. Three wire supply cables generally carry red and black hot wires of 110 to 120 volts each with a single white neutral wire. The first way of wiring uses a couple of two way light switches with a 3 wire control.
