The answer to 'switch circuit overload' is that a switch circuit overload is typically caused by too many electrical devices being connected to the same circuit, drawing more current than the circuit can safely handle. Symptoms may include the circuit breaker tripping, lights flickering or dimming, or the switch feeling hot to the touch.
To resolve a switch circuit overload, start by reducing the number of devices on the circuit. Unplug or turn off any non-essential devices and see if that resolves the issue. If the problem persists, you may need to have an electrician upgrade the circuit by installing a higher-rated circuit breaker or adding additional circuits to distribute the load. Attempting to bypass or overload a circuit can be extremely dangerous, so it's generally best to call a licensed electrician if you're unsure of the cause or how to properly address the problem.
