Hot wall switch

I recently installed a rheostat wall switch in a 3-way circuit for the ceiling lighting in my basement. I followed the directions carefully. I just noticed that the switch plate is very hot to the touch when the lights are on and cools when the lights are off. What causes this and what can I do about it? Is it dangerous? Marc

Dimmer switches will heat up in normal operation.

You said HOT.... Does this mean to hot to touch? Does it smell?

Warm is fine but if it is smelling or so hot that it is uncomfortable to hold your finger on it for more than a few seconds then maybe you have a problem.

Dimmers are rated for a certain load. How many lights does it run and what are their wattages?
