Unhappy Converting dimmer switch to standard switch!


My Father want's to replace a dimmer switch with a standard switch.
He has completely removed the old dimmer unit, which had two black wires and a dial control.
He thought this change over would be simple but we can't get anything to work.
The wall opening has 3 black wires and 3 white wires, all wires are seperated but I believe some of them were originally wrapped together.
Which two wires should we connect to the light switch?
What do we do with the other 4 wires?

A detailed description would be greatly appreciated.

We see this all the time. Unfortunately, wiring problems are a lot more difficult if you don't record how everything is connected before you start tearing it apart.

I suggest trial and error. Here's how:
  1. Shut off the breaker.
  2. Connect all three white wires to each other with a wire nut and push them to the back of the box.
  3. Select one of the black wires at random and connect it to one screw on the switch.
  4. Connect the remaining two black wires to each other with a wire nut, and to a pigtail to the other screw on the switch.
  5. Turn on the breaker and test.
  6. Worst case is that the switch will control more than it's supposed to, or will control the wrong things. If that's the case, start over and pick a different black wire in step 3. It won't take more than three tries to get it right.
Good luck.
