Manually operated switching device and transformation of a distance moved in an electrical signal

摘要

The switch has the manual displacement of the manual operating element converted into an electrical signal for the drive control, using switch contacts with a spring constant element. A first contact (7, 3) is operated after an initial free movement path of the operating rod (6), with a further contact (8) operated at the end of the working displacement path (7a) an electrical signal supplied between these contacts which is dependent on the displacement amplitude.
