静電容量タッチスイッチモジュール

摘要

PROBLEM TO BE SOLVED: To provide a capacitive touch switch module that has an electrostatic discharge protection circuit that can protect against electrostatic discharge and does not cause falsification even in other immunity tests.;SOLUTION: A capacitive touch switch module includes a capacitive touch switch panel 2, a control microcomputer 3 for controlling a signal from the capacitive touch switch panel, and an ESD protection circuit 4 disposed between the capacitive touch switch panel and the control microcomputer. In the ESD protection circuit, a resistive element 5 and a noise current interrupting element 6 are connected, and the resistive element is connected to the capacitive touch switch panel side, and the noise current interrupting element is connected to the control microcomputer side.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
