Abstract
A tact switch module is provided. The tact switch module includes a tact switch to control a driving voltage to be supplied to a power supply by sensing an ON input by a user; and a power control unit having a power input port which is connected to the power supply and a power output port to output a first voltage when power is supplied to the power input 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.
Claims12
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.
The tact switch module of claim l, further comprising:
- a first voltage distribution circuit which is connected to the output port of the power control unit and the power supply;
- and
- a second voltage distribution circuit which is connected to the first voltage distribution circuit and the switching port of the power control unit,
- wherein the first voltage distribution circuit and the second voltage distribution circuit distribute the first voltage, so that a voltage, which is inputted to the switching port, is less than the threshold voltage.
A power switching module comprising:
- a power supply;
- a tact switch to control a driving voltage to be supplied to the power supply by sensing an ON/OFF-input by a user;
- a power control unit having a power input port which is connected to the power supply, a power output port which 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 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,
- wherein the driving voltage triggers the power supply so that the power supply outputs the power, 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 the LOW after the predetermined delay time passes.
