Contactless electronic holding devices

The invention relates to ' _{kontaktlos® e} electronic Söhalt-O devices, in particular pushbuttons or switches *

Bekantlieh such have © contactless switching devices to such ,, where sur triggering an electrical puncture mechanical contacts necessary are _eight significant benefits ,, These consist except to less wear and therefore long life _it's that the transition .. resistant to the contact Gave birth remains constant " the contact »» -.'.- encoder-no .Versppgwngs-voltage required "switches bounce-free

and has no great expenditure on electronic components «In addition, the Gi'-v '& t is to a greater extent unapfindlloh against environment ₍ Si ₀ B * Vibration und -moisture” Such devices are particularly suitable for high switching frequency and great switching reliability «■

In the known embodiments of non-contact or kontaktXosen _e electronic Seteltgeräten SSOB "serves as Kon 'clock elnim switching condition, swinging Ossil" latorj whose vibrations inductive or capacitive werdenρ'um steamed / trigger a Schalfcvorgang * These inductive or capacitive systems allow Although a non-contact sensor fork own. However, the disadvantage / the great effort involved in ¹ . Components ^ They also need a supply voltage β are very temperature-sensitive and have to have a lot of effort to shield them to avoid interference to and from other devices; The application possibilities of such inductive or capacitive buttons or switches are therefore very limited in practice.

In order to remedy these deficiencies, the invention provides for contactless, electronic switching devices “In particular, pushbuttons or switches _6, one or more _{field sites that flow} through current and are connected to the output clergy and form rest and / or work contacts. a. Permanent magnets with pole _{piece in front of 9} whose ..position to the field plate can be changed by the movable device part for making contact «
