1. An actuator, comprising:
a drive device (2) which drives a drive shaft (1),
a first actuating element (3) operatively connected to the drive shaft (1),
a spring element (5) supported on one side on a housing component (16) of the actuator and on an opposite side on a second actuating element (17) configured for tensioning the spring element (5),
a rotational element (4) adapted to be driven by the drive shaft (1) and which is rotatably mounted, wherein the rotational element (4) has a first control cam (7), which is operatively connected to the first actuating element (3) and a second control cam, in which the second actuating element (17) engages for tensioning the spring element (5),
a further actuating element (12) for actuating a switching device, which further actuating element is operatively connected to the first actuating element (3), and a transmission device (8) with a transmission element (9) between the first actuating element (3) and the further actuating element (12) of the switching device.
