Capacitive contact switch for operating device of e.g. cooker, has elastic tab element which forms non-strictly monotonic force-displacement curve by its movement

摘要

The switch has carrier plate (12) with a sensor surface (14) and an elastic tab element (18,22) arranged on user side of a carrier plate. The elastic tab is partially in rest position and is moved towards the sensor surface of the carrier plate, if pressure is applied to touch switch. The non-strictly monotonic force-displacement curve is formed by the movement of elastic tab element.
