  • Switch modules for vehicle switches are known from the prior art in many ways.
  • a switch module is to be provided, which can be used in variously designed switching units use. It should be subject to low wear, have a simple mechanism and thereby allow a cost-optimal design in a minimum of space. The required switching power should be as low as possible, with different switching positions to be clearly identified. The generation of a switching signal should be carried out in particular contactless.
  • the invention proposes a switch module with the features of claim 1.
  • the switch module comprises a carrier which can be arranged on a printed circuit board, with a spring element supported on the carrier, and with an actuating part that is movably mounted on the carrier and can be acted upon by the spring element and brought into at least two switching positions, wherein at least one signal generator is provided on the control part, which interacts with at least one arranged on the circuit board signal sensor when arranged on the circuit board carrier.
  • a switch module consisting of the carrier, the spring element and the actuating part with the at least one signal generator, can be handled independently as a pre-assembly unit with or without a printed circuit board. In particular, it can be manufactured as a serial component in large numbers and be installed later in a variety of different types of switch units.
  • the signal transmitter is designed as a permanent magnet and the signal sensor as a magnetic field sensor.
  • a switching signal can be generated without contact. Due to the non-contact interaction of the permanent magnet with the magnetic field sensor, which may be formed for example as a Hall sensor, no high switching forces are required for signal generation and wear between the components generated the switching signal does not occur.
  • the poles of the permanent magnet can cooperate with the magnetic field sensor in such a way that the one pole is detected in the one switching position of the magnetic field sensor and the other pole is detected by the magnetic field sensor in the other switching position. This ensures that the magnetic field sensor is actively influenced in each of the switching positions. This is the result Generation of a switching signal guaranteed even with external interference magnetic fields.
  • more than two switch positions can be provided, wherein the permanent magnet then at least two transverse to the direction of the actuator adjacent, running in the direction of the actuator, each formed from individual north and / or south poles Polspuren, wherein for each Polspur on the circuit board own magnetic field sensor is provided. Consequently, with such an embodiment, a plurality of switching positions lying one behind the other in the direction of movement of the actuating part can be clearly recognized. About the binary output signals of the plurality of magnetic field sensors, a code can be determined, which is clearly assigned to a switching position. For example, two adjacent Polspuren be used, each Polspur is formed of four consecutive single poles.
  • each code word is assigned a clearly recognizable switching position. Accordingly, three adjacent poles tracks can be used, in which case three magnetic field sensors for scanning the respective Polspur are arranged on the circuit board. Overall, eight switching positions can be clearly identified.
  • the individual code words are such that between two adjacent code words of the binary code differs by only one bit. This allows a fault diagnosis to be realized; If the codeword changes by more than one bit or by no bit when moving the control part from one switch position to an adjacent switch position, a malfunction can be diagnosed.
  • the signal generator is designed as a light beam influencing diaphragm element and the signal sensor as a light sensor.
  • a non-contact signal generation occurs when moving the adjusting member relative to the signal sensor.
  • the diaphragm element may have at least two transverse to the direction of the actuating part adjacent, extending in the direction of movement of the actuating part, each formed from individual openings and / or closed sections glare trails, wherein for each glare on the Printed circuit board is provided a separate light sensor.
  • This also makes it possible to generate different binary code words depending on the switching position of the control. From the respective codewords can be deduced a unique switching position.
  • the signal generator is designed as an electrical contact bridge and that the signal sensor is designed as arranged on the circuit board contact path. Depending on the switching position of the switching part contacted the contact bridge via associated sliding contacts contact portions of the contact track. As a result, switch positions can be clearly identified.
  • the actuating part can in particular be motion-coupled with an actuating element via a guide section.
  • This has the advantage that the actuating part is not moved directly but indirectly via the actuating element from a switching position to an adjacent switching position. Consequently, the actuator can always be designed identically regardless of a later use of the switch module.
  • the switch module according to the invention can advantageously be used in a large number of differently designed switch units.
  • the guide portion of the actuating part may be formed as an obliquely to the direction of movement of the actuating part extending guide slope.
  • the guide bevel is advantageously arranged on the side facing away from the spring element of the actuating part. Due to this separation of functions results in a safe movement of the actuator against the force applied by the spring element spring force.
  • the actuating element is arranged movably mounted on the carrier.
  • the carrier provides for this bearing sections for the actuator.
  • the carrier has a latching connection for arrangement on the printed circuit board.
  • the carrier can be arranged in a simple manner positionally accurate on the circuit board.
  • the spring element may be formed according to the invention as a coil spring, plate spring, coil spring or the like.
  • it may be formed as a spring tongue, which is integrally formed on the carrier and / or on the actuating part.
  • the actuator moves along a straight line.
