摘要： A forced shutdown circuit includes a manually operable mechanical switch, a first switch circuit including a first switch connected between a power source and a load, a central processing unit (CPU), a second switch circuit including a second switch connected to the first switch, and a delay circuit connected between the mechanical switch and the second switch circuit. When the CPU is in normal, the CPU controls the first switch to be in an “on” or “off” state allowing the power source to power or disconnected from the load according to manual operation on the mechanical switch. When the CPU is in abnormal and the manual operation on the mechanical switch reaches a preset time, the delay circuit is activated to control the second switch to be in an “on” state or in an “off” state to control the first switch to be in the “off” state.
