Housing with a sensed power switch
A housing with a sensed power switch includes a shell, a motherboard power switch, and a sensed switch module. The motherboard power switch is located in the shell for turning on or off the computer. The sensed switch module is located in the shell, and has a sensing element and a control circuit. The sensing element is pasted onto the shell and corresponds to a sensing area located outside of the shell. The control circuit is electrically connected with the sensing element and the motherboard power switch. When a sensing object approaches the sensing area, the sensing element outputs a pulse signal to the control circuit. The control circuit outputs a control signal to control the motherboard power switch to turn on or turn off the computer according to the pulse signal.
