Abstract

Ein druckbetätigter Schalter zum Ein- und Ausschalten eines elektrisch betreibbaren Aggregats zur Druckerzeugung, mit einem durch ein unter Druck stehendes Medium mittelbar betätigbaren federbelasteten Schaltteil (2) zum Öffnen und Schließen von Schaltkontakten (6) und einem handbetätigbaren, als Drehknopf (4) ausgebildeten Ein-/Ausschalter, der mit einem axial bewegbaren Stößel (5) in Verbindung steht, über den das Schaltteil (2) betätigbar ist, ist so ausgebildet, daß der Stößel (5) verdrehsicher mit dem Drehknopf (4) verbunden ist und in einer durch den Stößel (5) bewirkten Unterbrechungsstellung der Schaltkontakte (6) verschiebegesichert ist, und daß das Schaltteil (2) mit einem durch den Mediendruck betätigbaren, federbelasteten und schwenkbaren Membranhebel (13) verbunden ist.

Figure 00000001
A pressure-operated switch for switching on and off an electrically operated unit for generating pressure, with a spring-loaded switching part (2) which can be actuated indirectly by a pressurized medium for opening and closing switching contacts (6) and a manually operated, designed as a rotary knob (4) - On / off switch, which is connected to an axially movable plunger (5), via which the switching part (2) can be actuated, is designed such that the plunger (5) is connected to the rotary knob (4) in a rotationally secure manner and in one by the plunger (5) effected interruption position of the switching contacts (6) is secured against displacement, and that the switching part (2) is connected to a spring-loaded and pivotable membrane lever (13) which can be actuated by the media pressure.
