Abstract
An automatic power off circuit of a non-rebound switch includes: a power switch circuit, the non-rebound switch, a trigger circuit, a controller, and a power on-off control circuit; the trigger circuit is connected with the power switch circuit and the non-rebound switch, and configured to send a turn-on signal to the power switch circuit to turn on the power switch circuit when the non-rebound switch is turned on; the controller is connected with the power switch circuit and configured to detect continuous turn-on time of the non-rebound switch and output a turn-off signal in response to the continuous turn-on time exceeding a preset timing time; the power on-off control circuit is connected with the controller, the power switch circuit and the non-rebound switch, and configured to turn off the power switch circuit by using the turn-off signal. A problem that non-rebound switches cannot be automatically powered off can be solved.
