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.
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).
