Abstract
An actuator includes two abutment elements and an adjusting device for changing their spacing in a translational displacement direction. A support element is provided between the abutment elements, a drive motor is supported by the support element, a first spindle nut is rotatably supported by the support element, a second spindle nut is rotatably supported by the support element, a first spindle engages the first spindle nut and is connected to one abutment element, and a second spindle engages the second spindle nut and is connected to the other abutment element. Two limit switches are mounted on a switch support on the support element and spaced apart from each other in the translational displacement direction. A first limit switch actuating element is attached to one of the abutment elements, and a second limit switch actuating element is attached to one of the spindles.
