摘要
An electrical circuit includes: a controlled switch; one or more temperature sensors in thermal contact with the controlled switch; and a control unit configured to: receive a temperature signal from the one or more temperature sensors; compare the received temperature signal to a predetermined threshold; and in response to the received temperature signal exceeding the predetermined threshold, render the controlled switch inoperative.
