Abstract (en)
[origin: US4827093A] A pressure switch has a plunger, axially displaceable by the pressure being measured, which enables a contact pin of a microswitch to be actuated. Between the plunger and the contact pin there is arranged a rocker. The microswitch is fastened to the housing of the pressure switch so as to be displaceable in the main extension direction of the rocker. This provides a way to vary the step-up ratio between the plunger motion and the contact-pin motion, whereby the magnitude of the hysteresis of the pressure switch can be varied.
