ROTARY SWITCH ASSEMBLY

摘要

An indexing system (1) for a rotary switch, comprises a housing (3; 13), a driving part (9) and a driven part (5), both being coupled to the housing for rotation with respect to the housing and with respect to each other about an axis of rotation (A). The housing and the driven part comprise cooperating first and second indexing means (119A, 119B; 33, 35) defining one or more relative angular positions. The indexing means comprise at least one first indexing member extending generally tangentially and/or azimuthally with respect to the axis of rotation and being at least partly reversibly movable between a first and a second radial position. In the first radial position the indexing means cooperate to block relative rotation of the housing and the driven part about the axis of rotation and in the second radial position the indexing means allow relative rotation of the housing and the driven part about the axis of rotation.
