Title:
ELECTROSTATIC CAPACITIVE SWITCH DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/094390
Kind Code:
A1
Abstract:
An electrostatic capacitive switch device 1 is provided with: a first signal output unit 4 that outputs a one-shot pulse signal on the basis of a sensor output; and a switch unit 7 that outputs a switch signal. The switch unit 7 outputs the switch signal in one shot by determining the presence or absence of the one-shot pulse signal through comparison with a threshold Th. The first signal output unit 4 is provided with an inexact differential circuit 25 that generates the one-shot pulse signal by differentiating the sensor output, and a reference-voltage supply circuit 27 that lowers the low level of the one-shot pulse signal to a level lower than the threshold Th by giving the inexact differential circuit 25 a voltage lower than the threshold Th as a reference voltage.
