It sounds like your dimmer is running hot, you can cheaply increase
the wattage rating of a dimmer just by replacing the plastic wall
plate with an aluminum wall plate, that will act as a good heat sink,
(but still doesn't mean you should exceed the max rating of the
dimmer). Plastic wall plates really stress dimmers that are running
above 70 percent of their rating. Or put a 1000watt dimmer on a 3
bulb fixture and it will run real cool if you're worried, maybe the
builder installed one rated too low for the bulb watts you have.
Since you said SWITCH, this is a very dangerous fire hazzard. I'd
disable the breaker for that switch till you find the cause, or work
on it NOW. Switches dont get hot, not even warm, unless there is a
fault. If however it's a dimmer, they normally get warm (not HOT).
What is it?
Either way, open the box and tighten all the screws (with power OFF).
Also look for broken wires and burn marks on the switch. Replace if
necessary. In fact, if it's just a common switch, spend the $2 and
