Abstract

Eine konstruktiv einfache, zur Erzeugung sicherheitsgerichteter Signale ausgelegte Taste (1) umfasst mindestens zwei durch manuelle Betätigung eines Betätigungsorgans (10) gemeinsam betätigbare, mechanisch entkoppelte Schaltelemente (2,3), wobei das erste Schaltelement (2) in betätigtem Zustand nach Art eines Wechselschalters einen in einem Ruhezustand geschlossenen Signalpfad (40) unterbricht und einen im Ruhezustand offenen Signalpfad (41) durchschaltet, und wobei das in den im Ruhezustand offenen Signalpfad (41) geschaltete zweite Schaltelement (3) diesen in betätigtem Zustand durchschaltet.
