ABSTRACT:
A key operating mechanism is embodied in an elongate housing having an axially disposed shaft defining a helical groove. A shaft end is provided with a key to which rotation is imparted by an actuator slidably disposed on the shaft. A drive member of the actuator cooperates with the helical groove in the shaft to impart rotation to the latter and may serve as a detent to prevent actuator movement. Spring elements, oppositely disposed from the actuator, serve to return the actuator to a neutral or static position wherefrom rotation in either direction may be imparted to the shaft. A thumb operated control button of the actuator slides within a housing defined slot during operation of the mechanism.
