A proximity switch is disclosed. In an embodiment, the proximity switch has a defined detection range and includes an oscillator, an oscillator amplifier, a temperature sensor, a microprocessor and a storage medium. The oscillator generates an alternating magnetic field and changes its oscillation state as a result of a target entering the detection range. The oscillator amplifier is configured to be controllable in an open-loop and closed-loop manner and has at least one amplifier stage. In this embodiment, the at least one amplifier stage has a controllable temperature compensation circuit which is configured to influence the oscillation behaviour of the oscillator based on compensation values received as control data from the microprocessor and/or from the storage medium, depending on a temperature detected by the temperature sensor. The disclosed embodiments also encompass a method for operating a proximity switch with temperature compensation.

The invention relates to an actuation device (3) for installing on a vehicle part (2), in particular in the form of a door or a hatch, having an electric switch means (30) with at least one switch element (31) for initiating a vehicle function and having a housing unit (10) with at least one first and second housing section (11, 12), wherein the second housing section (12) can be moved from a rest position (I) into an actuation position (II) at least in some regions relative to the first housing section (11) in order to actuate the switch element (31). The invention additionally relates to a vehicle (1) and to an actuation method (100).

A touch switch includes a touch input section, a metal piece provided to the touch input section at a surface thereof, and at least two induction-type proximity sensors so provided as to face the metal piece. The induction-type proximity sensors are arranged in parallel to each other and each have an LC oscillation circuit that output signals that changes in accordance with the distance to the metal piece. A duplicated touch switch that requires no stroke and achieves switch duplication is thus provided.

Apparatuses, methods and systems for an event-triggering apparatus are disclosed. One embodiment of the apparatus includes a sensor element operative to sensing a magnetic field, and apparatus control circuitry, wherein the apparatus control circuitry receives a representation of the sensed magnetic field. The apparatus control circuitry is operative to sense a deviation in the sensed magnetic field greater than a predetermined threshold, and trigger an event after sensing the deviation of the sensed magnetic field greater than the predetermined threshold.
