3-wire Light Switch

[keltong 4]

Hi,

I notice some light switch got 3 red wires. I change the switch and manged to get the lights working but just want to confirm as the old switch do not show any signs.

The lights switch got '1' and 'L', and the wires, 2 of them is connected together. So the 1 wire goes to which connection and the 2 wires together goes to which connection?

Thanks.

The two wires connected togehter are the power supply "live", be careful while handling them. There are two wires because it need to parallel out the power supply to another light within its group under the same breaker switch. The last light in the group will only have one such wire.

Now the other one wire is going to the light. So once you switch to "on" the supply will flow to the light. The "Neutral" and "Earth" wire of the lights are internally connected togehter, so you won't see these wires in the light switch.

Usually people will connect the 2 wires to the common ponit on the switch, the one wire will go to the "1" position. (for those switch with 2 way, for dual switching, the position "2" will have connecters too. But mostly we will see 1 way switch, and position "2" is left empty.)

Hope this helps. Cheers.
