Abstract
An electrical switch comprises a housing provided with at least one fixed contact part and one switching contact part, which moves in cooperation therewith. At least one actuating element is movably mounted in the housing. The actuating element influences switching positions of the switching contact part. Also disclosed is a camform which defines the switching positions and which interacts with a spring-loaded plunger associated with the actuating element in order to create operating forces. Moreover, a displaceable spring-loaded retaining device is disposed within the housing which enables the electrical switch to be held firmly in a locked position. Finally, at least one actuating element cooperates with a retaining device through a transfer device so that by use of increased force, the actuating element is brought into a functional position which does not correspond with any of the switching positions. The retaining device is brought into its unlocked position when the actuating element is in its functional position.
