Abstract

An actuating device for the mechanical positive actuation of a pressure-responsive switch utilizes a pivotably movable spring-loaded switch lever which, when activated by a control component movable in relation to the switch, is pivotable out of a lift-off position separate from the switch into a switch-triggering position bearing on the switch which is thereafter maintained in the bearing position. The switch lever is motionally coupled to the control component by spring force until the switch-triggering position is reached. It is possible to trigger the switch at an exact point, the switch lever is made bend-resistant and is pivotable about a joint and spring-loaded in the direction of its switch-triggering actuating advance. Since the switch lever is maintained in its switch-triggering position by the spring force, the control component can be moved further, uncoupled from the switch lever, after the latter has reached the switch-triggering position and moved through an additional angle to effect an additional mechanical function.
