Abstract
A rotary on/off control switch (100, 700, 900) provides improved torque with single click operation. Rotary on/off control switch (100) is formed of a casing (106), a drive member (108), and a carrier member (110) having frictional elements (112) coupled thereto. A lever (116) and drive member (108) provide rotation of the carrier within the casing. In response to rotation of the drive member (108), carrier member (110) and lever (116), each frictional element (112) travels against the casing generating torque for single click ON operation. Rotation past a predetermined angle causes the carrier member (110) to remain stationary for variable function control of the rotary on/off control switch (100). Reverse rotation of the drive member (108), carrier member (110) and lever (116), generates torque for single click OFF operation.
