how to install an electrical switch?
Answers:
Turn off the electricity first in the Breaker box. ;-) Have a Flashlight if it dark with no lights.Flathead Screw driver, remove the cover, remove two screws top and bottom from switch (They have a little plastic/fiber to keep them from falling out of the switch on other side), Pull Switch out of the Box slow and firm. Then touch both wires to be sure electric off, NO!! Ha! If, you not sure test with a volt meter set at 250 Volts AC. If it shows anything check breakers again. Unscrew the two/three wires and pay attention to what color go where!! If, it a light Switch may be a white and black wire. You may want some Needle Nose pliers to bend or adjust the wires. THIS is for Informational purposes only, I am not Responsible for Fried hair, dirty underwear or death. ;-D Good luck.

FIRST DETERMINE WEATHER OR NOT THE POWER SUPPLY IS OFF TO SWITCH BOX IN WITCH YOU ARE WORKING. THEN DETERMINE WEATHER THE POWER IS SUPPLIED AT THE SWITCH OR AT THE LIGHT. IF THE POWER IS AT THE SWITCH YOU WILL TYPICALLY HAVE A BLK./WHT.AND A COPPER GRD. THE BLK. IS TYPICALLY YOUR HOT WIRE IT WILL CONNECT TO THE TOP OF YOUR SWITCH AND THE BLK. WIRE FROM THE LIGHT FIXTURE WILL CONNECT TO THE BOTTOM OF THE SWITCH. THE WHT. WIRE IS YOUR NEUTRAL WIRE, IT WILL CONNECT TO YOUR WHT. NEUTRAL TO YOUR LIGHT FIXTURE. THE GRD. WILL GO TO EQUIP. GRD. SCREW. IF POWER COMES FROM THE LIGHT YOU WILL TYPICALLY HAVE A BLK./WHT.AND COPPER GRD. THESE WIRES ARE BOTH HOT WIRES ONE WILL CONNECT TO EACH SIDE OF THE SWITCH, AND THE GRD. TO GRD. SCREW
