Abstract:
The present invention relates to a linear actuator comprising a console, an outer tube connected to the console, an electric motor, a transmission, and a spindle in connection with the transmission. The linear actuator comprises a spindle nut on the spindle and an inner tube connected to the spindle nut. The spindle nut and the inner tube are guided inside the outer tube. The linear actuator comprises a control box which is connected to the console by means of a snap connection. The linear actuator further comprises an end stop arrangement having an end switch for each direction of movement of the spindle nut. An object underlying the invention is to provide a simpler connection of the control box to the linear actuator. A further object is to provide a less complex construction of the end stop arrangement of a linear actuator. To this end, the control box is connected to the console by means of a snap connection. Further, the linear actuator comprises a sliding element arranged between the spindle nut and the end switches, and where the sliding element is actuated by the spindle nut.
