Abstract:
1. An electronic device comprising: a front plate defining a receiving hole therein; a top plate covering a top side of the front plate; and a switch control unit comprising a mounting frame mounted on the front plate, a switch mounted in the mounting frame, a contact element located above the switch, and a control assembly, the control assembly comprising an inner knob rotatably received in the mounting frame, and the inner knob comprising an abutting portion protruding outwardly; wherein when the top plate completely covers the front plate, the top plate presses the contact element, and the contact element is resiliently held in a down position in which the contact element presses the switch and the switch is turned on; when the top plate is pulled away from the front plate, the contact element rebounds from the down position and moves upwardly to depart from the switch, such that the switch is no longer turned on by the contact element; and when the inner knob is rotated a predetermined first angle from a first position to a second position, the abutting portion abuts against the switch and keeps the switch on regardless of the position of the contact element.
