I have a room with no overhead lighting. The switch by the door controls a double 13amp socket where lamps can be plugged in. I would like to replace the existing switch with a brass one. There are 4 live and 4 neutral wires to the switch which has 4 large terminals to take them, a pair in each terminal. The switches I have found don't have 4 terminals. Anyone know what I need to ask for and where I might get one please?
