ELECTRONIC DEVICE AND SECURE SWITCH MODULE THEREOF

摘要

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 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.

主权项

1. A secure switch module for turning on an electronic device, the electronic device comprising a chassis and a motherboard received in the chassis, the motherboard comprising a power on pin and a ground pin grounded, the secure switch module comprising:
a lock secured to the chassis and comprising a core, a keyhole defined in the core, a first lock pin electrically connected to the ground pin, and a second lock pin; a key matching the lock; and a power switch secured to the chassis and comprising a first button, a first elastic conductive sheet electrically connected to the second lock pin, and a second elastic conductive sheet electrically connected to the power on pin; wherein when the key is inserted into the keyhole and rotated, the core is rotated along with the key to make the first lock pin electrically connect to the second lock pin; when the first lock pin is electrically connected to the second lock pin and the first button is pressed, the first elastic conductive sheet is electrically connected to the second elastic conductive sheet, the second elastic conductive sheet is grounded through the first elastic conductive sheet, the second lock pin, the first lock pin, and the ground pin in that order, the power on pin receives a low level signal from the second elastic conductive sheet, and the electronic device is turned on.
