Abstract
A switch assembly that includes the coaxial assembly of a cylindrical core extending from a base to a distal end, an outer knob rotatable about the core, a switching means generating an electrical signal dependent on the rotations of the knob, and a guiding means for guiding the knob in its motions relative to the core. The guiding means includes an upper-guide in the vicinity of the core-end and the knob-top, and a lower-guide in the vicinity of the core-base and the knob-base. The upper-guide includes elements rolling between an upper-guide inner race integral to the core and an upper-guide outer race integral to the knob.
