Home Improvements – San Jose – Electrical – Replacing a Switch
Replacing a standard one is fairly easy.
Often, the two wires are the same color, don’t let that bother you.
One wire is always hot, the other wire becomes hot when the switch it closed.
If you really want to know which is which, you can test with a $15 volt meter you can get at Orchard Supply.
The steps are:
- As with all electrical work, turn off the power at the circuit breaker.
- Disassemble the mechanism enough so the switch can pull out of the box.
- Take notes of where the wires connect.
- Disconnect the wires.
- If they are pushed into the back, you will need to cut them and strip them again.
- Reverse the steps for the new one.
- Don’t push the wires into the back – that connection type fails much more often then putting the wires under the screws.
- When you put the wires under the screws, bend the ends of the wires and place them under the screws such that tightening the screws helps the wires wrap around the screws – the wire should wrap around the screw in the same direction as the screw turns.
- When you are putting the switch back into the box, there is a right side up and an update side down – they should be on whey they are up, and off when they are down – you will see “on” or “off” or maybe both written someone on the front.
- Once the plate is on, power up the circuit and test your work.
