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. |

1. An actuator comprising:
a first abutment element and a second abutment element, and an adjusting device configured to move the second abutment element relative to the first abutment element in a translational displacement direction, wherein the adjusting device includes: a support element disposed between the first and second abutment elements in the displacement direction, a drive motor disposed on or in the support element, a first spindle nut rotatably supported on or in the support element, which first spindle nut is rotationally driven by the drive motor, a second spindle nut rotatably supported on or in the support element, which second spindle nut is rotationally driven by the drive motor, a first spindle which is in engagement with the first spindle nut and which is fixedly connected to the one abutment element, and a second spindle which is in engagement with the second spindle nut and is fixedly connected to the other abutment element, wherein two limit switches are disposed so as to limit the translational displacement path between the two abutment elements, and wherein the two limit switches are spaced in the translational displacement direction on a switch support, the switch support being attached to the support element, and wherein a first actuating element for one of the two limit switches is attached to one of the abutment elements and wherein a second actuating element for the other of the two limit switches is attached to one of the spindles. |
