ABSTRACT:
A push switch construction with an adjustable switching point which includes a piston or membrane adapted to be pressurized by a pressure medium and to actuate a switching element against an action of a restoring spring when a predetermined switching point is reached. The piston or membrane is operationally linked with a pivotably mounted switch lever which is adapted to actuate the switching element. The switch lever is tensioned by a leaf spring through a counter bearing displaced lengthwise relative to the switch lever in a direction opposite to a torque exerted by the piston or membrane.
