ABSTRACT:
A detent capture (26) is connected to the input shaft (16) of a position indicating transducer (10). A pair of leaf spring detents (24) are carried by a mounting base portion (14) of transducer (10). The leaf spring transducers (24) have at-rest positions in which they are received in, and interlock with, recesses (64, 66) formed in the detent capture (26). The leaf spring detents (24) serve to couple the detent capture (26), and hence the input shaft (16), to the transducer housing (12). This coupling occurs at a predetermined position in which the input shaft (16) is properly indexed to the electrical output of the transducer (10). The leaf spring detents (24) have outer end portions which contact a mounting member (22) as the transducer (10) is being installed onto the mounting member (22). This contact, and the movement of the transducer (10) into position on the mounting member (22), disengages the leaf spring detents ( 24) from the detent capture (26), freeing the input shaft (16) for rotation when the transducer (10) is mounted.
