I've just found out that the 1gang 1 way garage switch I wish to replace has 2 cables entering the switch box, I was expecting 1. One of the cables only seems to have a red wire coming out of it and is connected to the bottom of the switch, the other has an earth wire and a red wire connected to the top of the switch. Why are there no neutral wires?
Also instead of just replacing the old switch I wanted to extend the cable further up the garage to the new switch for convenience. I intended to put a 20 amp junction box where the old switch is and new cable from the box to the new switch. In the junction box is it ok to connect the new T&E blue wire to one of the old red wires, and the new brown wire to the other red wire, and the new earth to the old earth wire? Then the new blue and brown wires to the bottom and top connectors in the new switch. I don't know much about electrics so maybe that's all wrong. Would value any help.
Because, like almost all light switches, it is a single-pole switch. It only switches the live. You can take the neutrals to the switch box,Why are there no neutral wires?
Yes, but sleeve the blue with brown.Inthe junction box is it ok to connect the new T&E blue wire to one of the old red wires, and the new brown wire to the other red wire, and the new earth to the old earth wire?
You really, really, REALLY ought to learn something. Trying to do electrics without actually understanding what's going on is incredibly foolish.I don't know much about electrics
In the photos the existing switch looks like it is white plastic, which does not rust.I don't want to use the existing switch as it is very rusty.
