Two Way Wiring A Light Switch Uk Diagram. As you can see in the schematic diagram of 2 way switch circuit below the common of both the switches are short circuited. Connect the blue wire with the brown slewing coming from the light to the l2 terminal together with the 3 core earth cable grey wire.
This arrangement is often found in stairways with one switch upstairs and one switch downstairs or in long hallways with a switch at either end. 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. 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.

Also the same wiring circuit diagram can be used using 2 way lighting or two way switches to control electrical devices from two different locations.
