Abstract

The invention relates to switching devices with contactless switching mechanism, in particular used in switching devices whose switching mechanism to avoid wear of the contacts and to reduce the maintenance effort is to be operated contactless. The solution of the problem is achieved in that a permanently attached to the switching mechanism of the switch permanent magnet or a fixed solenoid current-carrying solenoid is brought into the sphere of influence of a bipolar Hall generator circuit with appropriate Betetigung the switching mechanism, whereby the binaere output level of said circuit changes. figure

Description

Scarf works with. contact loose scarf tmechanisnms field of application of the invention

The invention relates to switching devices with contactless switching mechanism, in particular used in switching devices whose switching mechanism sum avoiding the Verschleiszes the contacts, to increase their Detriebszuverlaessigkeit and to reduce the maintenance costs to be operated contactless.

Characteristic of the known technical solutions

Schaltgeraete are known in which the switching on or interrupting the flow of current based on the closing or opening of Kontaktflaechen. The disadvantage here is that this causes a Verschleisz the Kontaktf1aechen, which has a Betriebunzuverlaessigkeit and maintenance work.

Object of the invention

The object of the invention is to avoid contact wear and tear during maintenance of contact-type switching mechanisms, and to increase the reliability of the operation and to increase reliability of operation.

Explanation of the essence of the invention

The invention is based on the object of avoiding the disadvantages of the contact-type switching mechanism of switching devices by using an electronically switching component.

The invention is achieved by changing the final state of the activation level of a bipolar semiconductor generator circuit by acting on a permanent in the magnetic field when the switching mechanism of the contact-type switching device is operated. The solution is achieved by a permanent magnet attached to the switching mechanism of the switch or a permanent current-carrying? Magnet coil is brought into the sphere of influence of a bipolar Hai 1-Oenerator circuit with appropriate Betetigung thereof, whereby the binaere output level of the aforementioned circuit changes without scarf t contacts on the scarf tgeraet beta have been ^eliminated .

Execution example

The invention will be explained in more detail on an exemplary embodiment. The appended drawing shows the inventive solution using the example of a contactless push-button.

By pressing the switching mechanism 1 from the key position A in one of the key positions E ₁ or E ₂ is a sylinderfoermiger permanent magnet 2, which is mounted on a non-magnetic carrier 7, in the sphere of influence of a bipolar HaIl generator Scnal tkreises 3 or 4 brought (pivoted ), whereby at the connection 1 lines 5 or 6, the aforementioned circuits, the applied output level changes.
