Detecting unit for contactless determination of at least two positions of switching element - has magnetically or optically working transmitter and receiver and transmitter or receiver brought into positions to be detected by switching element

摘要

The positions to be determined are provided respectively with assigned receivers (8,9,10) or transmitters. The transmitter (4) or the receiver is movable by the switching element (2) on a curved surface. The receivers or transmitters assigned to the positions to be determined are arranged on one platinum board (7). Conducting elements (5,6) for magnetic flux or light are arranged between the transmitter (4) or the receiver, found in the position to be determined, movable by the switching element, and the assigned receiver or transmitter. Ferromagnetic screws (31,33,35) are used as conducting elements and are arranged in a carrier (24). The switching unit (2) can be a gear selector for a drive. ADVANTAGE - Type unit improved so that construction is simplified and assembly of sensors (32,34,36) is easier.
