ABSTRACT:
An index rotary switch includes a housing, stationary contact members, a rotor contact member, and a pushbutton-operated actuator device. The stationary contact members are disposed within the housing for defining an infinite number of alternately achieved on-and-off positions. The rotor contact member is disposed for rotation within the housing for wipingly engaging the stationary contact members. The rotor contact member is formed with a rectangularly-shaped flat portion and a plurality of resilient L-shaped arms extending downwardly from respective edges thereof. The L-shaped arms have arcuate-shaped contacts formed upon their free ends so as to wipingly engage the stationary contacts. The actuator device is disposed within the housing and is operatively connected to the rotor contact member for sequentially rotating the rotor contact member so that the arcuate-shaped contacts alternately index with respect to the on-and-off positions upon successive actuations of the actuator device.
