Abstract

A manually operated angle pickup or detector has a rotatably mounted and manually movable transmitter element, a sensor that scans the transmitter element and a detent coupling that operates magnetically and in a contactless manner to maintain the transmitter element in defined angular positions which can change from one to another by manual operation. The detent coupling includes at least one permanent magnet with poles disposed in the axial direction and two toothed disks provided on the side of at least one pole of the permanent magnet. The two toothed disks are radially spaced and have a corresponding number of teeth. The disks are interconnected by the magnetic flux and are of a material with good conductivity.
