Title:
操作スイッチ
Document Type and Number:
Japanese Patent JP6793365
Kind Code:
B2
Abstract:
An operation switch includes: an electrostatic capacitance sensor that generates a sensing signal in response to approach or contact of an object; and a controller that determines whether or not the object is a human body in accordance with the sensing signal. The controller determines that the object is not a human body, when (A) a magnitude of the sensing signal is larger than a first threshold at a first time point, (B) a rate of change in the magnitude of the sensing signal in a first period is larger than a first rate, and (C) the magnitude of the sensing signal does not fall below a second threshold in a second period subsequent to the first period.
