Abstract
A secure switch module to allow only authorized keyholders to power on an electronic device includes a lock, a key matching the lock, and a power switch. The lock includes a first lock pin electrically connected to a ground pin of a motherboard of the electronic device, and a second lock pin. The power switch includes a button, a first elastic conductive sheet electrically connected to the second lock pin, and a second elastic conductive sheet electrically connected to a power on pin of the motherboard. When the key is engaged with the lock and the button is pressed, the first lock pin is electrically connected to the second lock pin, the first elastic conductive sheet is electrically connected to the second elastic conductive sheet, the power on pin receives a low level signal, and the electronic device is turned on.
