I've been trying to figure out how to do this and I'm slowly getting there. I wasn't able to buy just the light switch itself, I had to buy the whole unit with one black wire and one white wire coming out top. I'm assuming that has to go back up into the fan unit but I'm stumped as to how I get the bottom part removed to get at the wires underneath. There's 4 screws around the perimeter and I tried to unscrew without any luck. You have the (4) blades for the fan and underneath that is the enclosed unit that contains all the wires. I'm trying to figure out how to get that off so I can reroute the wires from the ceiling fan light kit...

Thanks in advance...
