Abstract
The invention relates to an actuator, comprising a drive (2) that drives a drive shaft (1), a first actuating element (3) operatively connected to the drive shaft (1) for actuating a switching apparatus, a spring element (5), which can be supported at one end on a housing component (16) of the actuator and is supported on the other end on a second actuating element (17) designed to load the spring element (5). The actuator according to the invention is characterized in that a rotatably mounted rotational element/gearwheel (13) that can be driven by means of the drive shaft (1) is provided, which rotational element has, on one side, a first control gate (7), which is operatively connected to the first actuating element (3) for actuation of the switching apparatus, and on the other side, a second control gate (8) for loading the spring element (5).
