Abstract: A position signal transmitter (1) for indicating the position of a servo drive includes a housing (2) adapted to be connected to the servo drive, and a switching shaft (4) that is rotatably supported in the housing and adapted to be coupled in a positive manner to an operating shaft of the servo drive. At least one switching cam (24A, 24B ) provided with an internal gearing (28) is mounted on the shaft (4) so that the internal gearing (28) engages an externally geared section (29A, 29B ) of the wall of the shaft (4). The externally geared section (29A, 29B ) of the shaft wall is elastically deflectable in a substantially radial direction toward the central rotational axis (30) of the switching shaft (4). One or more mechanical or inductive switches are mounted in the housing (2) to be cooperatively actuated by the switching cam.
