PURPOSE: A debounce switching device embedding a debounce circuit is provided to improve the property of the whole circuit by efficiently removing a debounce. CONSTITUTION: A button(200) is prepared for switch on and off. A leaf spring(210) is installed on the lower side of the button. A debounce circuit chip(240) includes a debounce circuit which electrically removes bounce generated by physical elasticity in the on and off of a switch. First to fourth terminal pins(222,224,226,228) are connected to a debounce circuit chip. A first terminal pin is connected to a first output terminal(252). A fourth terminal pin is connected to a second output terminal(254). A third terminal pin is connected to the GND of the embedded debounce circuit through one contact(234) of the switch. |
