The switch heat can either come from the switch contacts, or loose push on connectors, or (best case)= simple heat from the heater. If the small, cheap rocker switches, a lot of those imports have a high failure rate when new; my Amazon had 3/12 bad in light switches. But also need to verify switch RATED for 120vac?
