Abstract

Es wird vorgeschlagen eine Anordnung (10) zum berührungslosen Schalten eines elektrischen Kontaktes (12) mittels einer eine vorbestimmte Schaltkraftschwelle übersteigenden Schaltkraft (17), mit

  • einem Schaltglied (14), mittels dessen die Schaltkraft (17) ausgeübt wird,
  • einer an einer Einspannstelle (C) einseitig eingespannten Blattfeder (38), wobei das Schaltglied (14) zum Schalten an der Blattfeder (38) angreift, um die Blattfeder (38) von einer Ruheposition in eine Schaltposition (48') zu bewegen, wobei die Blattfeder (38) in der Ruheposition so angeordnet ist, daß deren Federkraft (51) die vorbestimmte Schaltkraftschwelle bildet.
An arrangement (10) for contactless switching of an electrical contact (12) by means of a switching force (17) exceeding a predetermined switching force threshold is proposed
  • a switching element (14) by means of which the switching force (17) is exerted,
  • a leaf spring (38) clamped on one side at a clamping point (C), the switching element (14) engaging for switching on the leaf spring (38) in order to move the leaf spring (38) from a rest position into a switching position (48 '), wherein the leaf spring (38) is arranged in the rest position so that its spring force (51) forms the predetermined switching force threshold.

Dabei sind Mittel (58; B) zur Veränderung der Lage (C1, C2) der Einspannstelle (C) vorgesehen, so daß durch Veränderung der Lage (C1, C2) der Einspannstelle (C) die Schaltkraftschwelle eingestellt werden kann (Fig. 1).

Figure 00000001
Means (58; B) for changing the position (C 1 , C 2 ) of the clamping point (C) are provided so that the switching force threshold can be set by changing the position (C 1 , C 2 ) of the clamping point (C) ( Fig. 1).
