Abstract

Ein Dreilagenhandgriff für eine Robotersteuerung ist mit einem Drucktaster (T) versehen, der sicher die folgenden Funktionen auslöst: Drucktaster (T) nicht gedrückt - Stoppfunktion, Druck­ taster (T) in Mittellage - Freigabesignal, Drucktaster (T) voll gedrückt - Stoppfunktion. Dazu ist eine Kontaktanordnung (K,KS) vorgesehen, die einen Schließerkontakt (KS) aufweist, der ausgehend von einer Stoppfunktion beim Nichtbetätigen des Tasters (T) beim definierten Betätigen das Freigabesignal be­ wirkt und der über eine mechanische Umlenkung (G,HE,ST) beim krampfartigen Betätigen den Schließerkontakt (KS) in die Aus­ gangsstellung zurückbewegt. A three-layer handle for a robot controller is with one Pushbutton (T) provided that safely the following functions triggers: pushbutton (T) not pressed - stop function, push Push button (T) in the central position - release signal, push button (T) fully pressed - stop function. There is a contact arrangement for this (K, KS) is provided, which has a normally open contact (KS), starting from a stop function when the Push button (T) when activating the defined signal acts and via a mechanical deflection (G, HE, ST) at spasmodic actuation of the normally open contact (KS) in the off gear position moved back.
