摘要

The device (10) has a housing (12) provided with a spindle (14), an electric drive (16) i.e. synchronous motor, and an adjustable device (18) e.g. shutter board or prism closure exhibiting switch positioning device. The electric drive is fixed with control rods (20, 22) in active state. The control rods are connected with tongue rails. The spindle is fixed with the electric drive, and coaxially moves along the adjustable device. A rotor of the electric drive is fixed with a spindle nut of a screw thread shoot. A stator is connected with the housing and the electric drive.
