  • Patent number: 4348569
    Abstract: A rotary switch construction wherein a stator has a pocket for receiving a rotor. The rotor has a flexible rim which permits it to snap-fit into the pocket of the stator. A plurality of angled surfaces on the stator compress the rotor rim as it is inserted into the pocket of the stator. Retainer means are provided to hold the rotor in the stator. The rotor further includes a plurality of stop pairs. The stator has a single, fixed stop which is disposed between the stops of one of the pairs on the rotor. The rotor stops have variable arcuate spacing so that, depending on which pair of stops spans the fixed stop, the degree of rotational freedom of the rotor can be selected. In another aspect, the rotary switch includes means on the rotor for fastening the rotor blade in place.
