Patent ID: 8766121

Claim:
A rotary on/off control switch, comprising: a casing; a shaft providing greater than 180 degrees of rotation; a drive member coupled to the shaft; a carrier member having a plurality of frictional elements coupled thereto; a lever coupled to the carrier member and detachably coupled to the drive member; and the shaft, the drive member, the carrier member and the lever rotatably coupled within the casing such that rotation of the shaft causes rotation of the drive member, rotation of the drive member transfers motion to the lever, and the lever transfers motion to the carrier member over a predetermined range of rotation of the shaft within which the plurality of frictional elements travel against the casing thereby generating a single click with torque for on/off operation, and further rotation of the shaft beyond the predetermined range rotatably decouples rotation of the drive member and the shaft from rotation of the lever and the carrier member.
