ABSTRACT:
A control knob is secured to a D-shaped shaft or lever of a switch or potentiometer which is supported on a control panel. The control panel is molded plastic and is furnished with detent ramps or indentations in its surface adjacent the shaft or lever. A D-spring between the knob and the shaft retains the knob in the shaft and has a laterally extending leaf spring with a detent button formed in the leaf near its free end. The leaf spring biases the detent button against the detent ramps to afford detent action upon rotation of a shaft or linear movement of a lever. The detent ramps are formed in a forward-facing surface of the panel or in a wall formed by a recess or aperture in the panel. The leaf spring is shaped to accommodate the position of the detent ramps.
