Patent ID: 7745958

Claim:
A tact switch module comprising: a tact switch to control a driving voltage to be supplied to a power supply by sensing an ON/OFF input by a user; and a power control unit having a power input port which is connected to the power supply, a power output port to output a first voltage when power is supplied to the power input port, and a switching port to control HIGH/LOW switching of the output port and switch the output port to the LOW when a voltage greater than a predetermined threshold voltage is supplied to the switching port, wherein the driving voltage triggers the power supply to output the power, and the power supply supplies the power to the power input port while the first voltage is supplied from the power output of the power control unit, and wherein the power control unit ignores the power, which is inputted to the switching port, during the predetermined delay time when the tact switch module senses, from an ON mode, an OFF-input by a user, and the power control unit switches the output port to a LOW after a predetermined delay time passes.
