ABSTRACT:
A mechanical limit sensing device or limit switch for piston and cylinder actuators has a housing in which a rocking lever is pivoted so that its one end is moved by part of the actuator to be controlled. The other end works a switching element. The housing is made in two parts, that is to say on the one hand a bush or bearing sleeve and on the other hand a gripping or clamping body for the bush. The bush may be turned in the body and may be clamped in it in a given position. The lever has a ball-like part with which it is mounted in a socket in the bush. The lever is furthermore guided in a slot in the body. This slot furthermore divides part of the body into two jaws that are used for clamping the body onto the bush. The switching element is screwed into a hole in the body that is in the same plane as the slot. There is furthermore a blind hole in this plane to take up a plunger for returning the lever after being actuated.
