Replacing Switches

How to Replace Switches and Receptacles

Replacing switches and receptacles can be as easy as 1,2, 3. Follow these steps for a seamless installation.

You can replace switches two different ways: pushing bare wires into holes in the back of the device or by wrapping the wires around screw terminals on one or both sides. Most electricians believe wrapping around the screw terminals provides a more secure connection. Many also wrap electrical tape around the switch as well for increased safety.  Because of this, we have included it in our steps for replacing both switches and receptacles.

Steps for Replacing a Switch

1)      Shut off power to the circuit. Remove the cover plate. Remove the screws while holding the switch to the box and gently pull out the switch. Loosen the screw terminals or push a nail into the wire-release holes. Disconnect the wires.

2)      Inspect the wires in the box and wrap and damaged insulation with electrical tape. Attach the wires to the terminals of the new switch. Wrap electrical tape around the body of the switch to cover the terminals.

3)      Fold the wires back carefully and fasten the switch to the box with the mounting screws. Do not force the unit. Switches can break and short out from the pressure exerted from forcing wiring.

Similar to switches, there are two ways to replace receptacles: wiring receptacles through holes or screw terminals on the sides. Also like replacing switches, the screw terminal holds better and so most people choose this option.

Steps for Replacing a Receptacle

1)      Turn off power to the box. Pay attention to which wires are attached to which terminals. You may want to make notations on tape attached to the wires, especially if this is your first time replacing a receptacle. Loosen the terminal screws or push a nail into the wire-release holes and disconnect the wires.

2)      Look at the wires in the box and with electrical tape, wrap any that appear damaged or have insulation missing. Attach the wires to the terminals. Position each wire so it hooks clockwise from on the terminal screws. Tighten the terminal screws.

3)      Wrap the body of the receptacle with electrical tape covering it in entirety—all terminals included. Using caution, tuck the wires and the receptacle back into the box and attach the receptacle to the box with mounting screws. Do not force the receptacle; it can crack.
