Abstract: At least a motor, a gear unit and an adjustment connection form an actuator. The gear unit is fitted with at least two mutually movable gear parts, as well as a spring acting on two of these that counteracts their movement out of an idle state. The gear unit is designed such that when an adjustment connection is blocked the motor moves the gear parts out of the idle state during operation to an operating point. In addition, the gear unit is designed such that during the movement out of the idle state it reduces the extent to which the movement is counteracted from a particular point upstream of the operating point.

Abstract: A motor and a gear unit form an actuator. The gear unit is fitted with at least two mutually movable gear parts, acted on by a spring that counteracts their movement out of an idle state. The gear unit is fitted with at least one manual actuator that when actuated switches the motor off, disengages two mutually interacting gear wheels of the at least two gear parts and forces the at least two gear parts into the idle state. When the motor moves the gear parts out of the idle state during operation to an operating point, a cam plate on a first gear part is contacted by a sensor element on a second gear part, and the spring acts on the first and second gear parts during the movement out of the idle state in accordance with a position on the cam plate of the sensor element.

Abstract: Such an electrical device (6) comprises an electrical module (8) for the purpose of communicating between the electrical module (8) and another electrical device. An identification transmitter (14) is provided which has a first position, in which the electrical module (8) is in a non-operative state, and a second position, in which the electrical module (8) is in an operative state. In addition, an identification pick-up (20) is provided which interacts with the identification transmitter (14) in the second position in order to evaluate information defined by the identification transmitter (14). The electrical device (6) makes possible, inter alia, an alternative addressing concept in which the location of a fixedly installed base (12) or the wiring to the base (12) is addressed, since the information transmitter (14) is located on the base (12).
