Abstract
A switch assembly () includes a rotary electrical switch body () having a plurality of switch positions, a switch stem () extending along a first axis () and having a first and second ends, the first end engaging the rotary switch () for alternating the rotary switch body between the plurality of switch positions responsive to rotation of the switch stem about the first axis, and a knob assembly (). The knob assembly includes a knob core contacting the second end of the switch stem, a knob collar () contacting the knob core and adapted for rotating the knob core and the switch stem about the first axis, where the knob collar includes a first upper stop member (), and a stop cam () having a fixed position relative to the switch stem and disposed between the knob core and the rotary switch, where the stop cam includes a lower stop member () having a feature for engaging the first upper stop member when the first upper stop member and the lower stop member are disposed along a common path. In the switch assembly, the first upper stop member travels in a circumferential path normal to the first axis responsive to the knob collar rotating the knob core and the switch stem, where the knob collar is displaceable along the first axis between first and second axial positions, where the lower stop member is in the circumferential path when the knob collar is in the first axial position, and where the lower stop member is removed from the circumferential path when the knob collar is in the second axial position.
