Abstract:
1. A control knob return/detent mechanism, comprising: a) a frame assembly including a detent surface formed therein, a plurality of end stops, and a plurality of return spring locators; b) a return/detent rotor assembly operably positioned relative to said frame assembly, comprising: i) a detent rotor including a plurality of rotor located spring stops; ii) a pair of opposing detent springs positioned within said detent rotor; and, iii) a pair of detent balls, each detent ball being biased toward said detent surface by a respective detent spring; c) a return/detent mechanism rotatable shaft operably positioned within said return/detent rotor assembly and operably connectable to an encoder element, said detent rotor and said return/detent mechanism rotatable shaft being rotatably stationary relative to each other; d) a return spring positioned about said rotatable shaft and operably positioned relative to said plurality of return spring locators and said plurality of rotor located spring stops to bias said return/detent mechanism rotatable shaft and said detent rotor in a normally centered position,
