ABSTRACT:
A rotary switch having a rotor and a housing and providing a plurality of angular switch positions or stages. The switch includes a plurality of radial slots in the housing having stop pins selectively inserted therein. The angular spacing between neighboring slots is twice the position angle or rotation from one switch position to the other. One or two stop bolts are mounted on the rotor at angular positions between the angular positions of a selected pair of stop pins in the housing. The stop bolts are separated from one another by a spacing equal to the position angle of rotation. The stop bolts engage the stop pins to limit the desired number of stages or switch positions. By selecting a corresponding combination of one or more stop pins and the arrangement of one or two stop bolts, any odd or even number of switch positions, each separated by the minimum angle or rotation, can be selected.
