The answer to 'switch power surge' is that a power surge through an electrical switch can be caused by a variety of factors, including lightning strikes, electrical grid issues, or faulty wiring. Symptoms may include the switch feeling hot, sparks, or the switch tripping the circuit breaker. To address a switch power surge, the first step is to turn off power to the affected circuit at the breaker panel. Then, inspect the switch for any visible damage or signs of overheating. If the switch appears damaged, it should be replaced by a qualified electrician. If the switch seems fine, the issue may be with the wiring or a larger electrical problem, which should also be evaluated by a professional.
In general, it's best to call an electrician anytime you experience a power surge or other electrical issue, as they have the expertise to properly diagnose and fix the problem safely. Attempting DIY electrical repairs can be extremely dangerous if you don't have the right training and experience.
