Installing a dimmer switch is not as difficult as one might think! The first step is turning off the breaker that supplies power to the light fixture you want to dim. Once the breaker is off, remove the cover plate and unscrew the two screws that hold the light switch in place. After removing the old light switch, connect all the black wires together, all the white wires together, and then twist on a wire nut. Finally, reattach the cover plate and screw in your new dimmer switch!
