Son just moved into a house and wants to replace a 2 gang touch sensitive light switch in the living room which has failed. There is also a touch sensitive light switch 2 gang in the understair cupboard that's failed that is linked to the living room and can switch off/on the living room lights. I can't think why there is a switch in the understairs so would like to remove it join the wires and put a blanking plate over it. Anyone have a clue why there is an extra switch, thought it maybe to do with the touch sensitive switch needing a neutral.
