Capacitive proximity switch, and domestic appliance equipped with the same |
摘要 |
A capacitive proximity switch has an electrically conductive sensor surface, which is covered by an electrically non-conductive covering plate and which serves as a part of a capacitor with a capacitance that varies with proximity. A household appliance is equipped with a proximity switch of this type. The sensor surface has an active shielding, which is formed by a shielding surface to which a clock signal is applied at the same time as it is applied to the sensor surface.
