How to Replace a Wall Switch in 10 Steps


Insert Wires

If you're installing modern wire-grip type of wall switch, cut off end of each wire to leave only 1/2 inch of bare wire. Push one bare end wire into each wire-grip hole, and check that wires have caught properly by tugging gently on them. Caution: If wires or insulation going into electrical box are brittle or frayed, that part of circuit should be professionally rewired.
