The answer to 'switch gets hot' is that a hot switch is typically caused by a problem with the electrical circuit or the switch itself. This can be a sign of an overloaded circuit, loose connections, or a faulty switch. If a switch is getting hot to the touch, it's important to address the issue promptly to prevent further damage or potential fire hazard.
Some common causes of a hot switch include: high electrical load on the circuit, a short circuit, loose or corroded connections, or a switch that is simply worn out and needs to be replaced. Symptoms may include the switch feeling warm or hot to the touch, flickering or dimming lights, or tripping circuit breakers. To troubleshoot and resolve the issue, it's best to start by checking the circuit load and connections, and potentially replacing the switch if it's faulty.
