Title:
PRESSURE SENSITIVE ELECTROSTATIC SWITCH DEVICE AND ELECTRICAL DEVICE
Document Type and Number:
Japanese Patent JP2019029160
Kind Code:
A
Abstract:
To provide a pressure sensitive electrostatic switch device capable of detecting various operations by an operating body.SOLUTION: A pressure sensitive electrostatic switch device includes an insulating panel to be operated by an operating body, a detection electrode provided on the back surface of the insulating panel so as to correspond to an operation region, a drive electrode disposed on a circuit board so as to face the detection electrode, an AC signal supply unit for supplying an AC signal to the drive electrode, and a circuit device having a reception signal detection unit for extracting a reception signal from the detection electrode, and the circuit device analyzes the reception signal detected by the reception signal detection unit and detects proximity, touching, and pushing of the operation body to the insulating panel.SELECTED DRAWING: Figure 5
