According to an advantageous embodiment of the invention, the conductors each have a stop, which is adapted to limit the movable storage. Thus, an excessive load can be prevented.

According to an advantageous embodiment of the invention, the conductors each have at least one bend, in particular at least two bends. Thus, forces can be very gently absorbed for the connector. The bend may be formed, for example, meandering or S-shaped.

If the ladder has two bends, the absorption of forces from different directions can be decoupled. Accordingly, a first bend may be provided to accommodate movements of the actuator and a second bend may be provided to accommodate movements of the circuit board.

According to an advantageous embodiment of the invention, a first bend forms a bulge in a first direction and a second bend forms a bulge in a direction opposite to the first direction. Thus, tensions between the bends can be better compensated.
