One Way Two Gang

Let say when you go to your room and you have these switch and you wonder how the heck this switch works. You may think this switch like a twin. yes it's like twin and work in same way,but control different loads like light bulb. This switch called one way two gang. Yeah they are gang!!! that's why they control different loads.

One way two gang works similar to single one way switch. In this switch there's two one way switch join together. The reason these switches join is to reduce space and the cost. This switch has 4 connection, 2 (COM) 2 L1 (LIVE 1). It's like two one way switch join. The wiring for this switch is simple. Lets look at it.

The 2 COM terminal are connect to each bulb and 2L1 are loop in and connect to MCB. The reason why the 2 L1 loop in because the power from MCB will distribute to 2 switches. so you no need the 2 MCB to power the switches.

You know right why this one way switch are join. Now you can play with these switch to switch on and off bulbs. Hope don't blow up the bulb :P
