The answer to 'dimmer switch hot to touch' is that a dimmer switch that is hot to the touch is often a sign of an electrical issue that requires attention. This can be caused by several common problems, including overloading the dimmer switch, a faulty switch, or improper installation.
When a dimmer switch gets hot, it indicates that too much electrical current is flowing through the switch, causing it to overheat. This can be due to using a dimmer switch that is not rated for the wattage of the lights it is controlling, or having too many lights connected to the dimmer. Another potential cause is a malfunctioning dimmer switch that is not properly regulating the flow of electricity.
