DEBOUNCE SWITCHING ELEMENT INCORPORATING A DEBOUNCE CIRCUIT

摘要

The present invention relates to a debounce switching element incorporating a debounce circuit, wherein the switching element comprises a button; a leaf spring provided below the button; a debounce circuit for electrically eliminating bounce generated by physical elasticity at the time of switching on or off; at least three terminal pins comprising a 1^st terminal pin, a 2^nd terminal pin and a 3^rd terminal pin connected to the debounce circuit; and a switch body which incorporates a debounce circuit and has an opening providing a space where the leaf spring and the button can be fitted, and wherein the debounce circuit comprises a 1^st output terminal connected to the 1^st terminal pin, a VCC terminal which is connected to the 2^nd terminal pin and to which VCC is input, and a grounding terminal connected to the 3^rd terminal pin and to the GND, and also wherein the two switching contact points are connected to each other by means of pressing of the leaf spring due to the button being pressed, and, if the button is not pressed, restoration of the leaf spring causes disconnection of the two switching contact points, and one contact point connects to the VCC terminal and the other contact point connects to the grounding terminal. According to the present invention, it is very straightforward to design a circuit in which a switch is used by a user, since there is no need to add a debounce circuit to a switching element separately, and the features of the whole circuit can be improved by eliminating debounce efficiently since the invention incorporates a circuit which is very well matched for the features of the debounce generated by the mechanical contact of the switch.
