A rotary circuit component with a rotatable shaft is secured to a mounting structure so that rotary motion of the shaft and axial motion along the shaft are prevented in part by a mating slot and notch, fastening means, and terminal tabs on the component soldered to slits in a printed circuit board.
Claims6
A rotary circuit component assembly in which the rotary circuit component is secured and locked in position, comprising:
- a. a rotary circuit component including:
- 1. a body which houses the component elements that determine the characteristics of said component;
- 2. a shaft defining a rotational axis of said rotary circuit component, and rotatably mounted to said body to engage said elements in said body for the purpose of altering the characteristics of said component;
- and
- 3. a cylindrical bushing positioned around said shaft and attached to said body, said cylindrical bushing having a slot defined therein;
- b. a mounting structure including a notch which is dimensionally compatible with said slot, for receiving said cylindrical bushing at said slot such that said slot and notch are aligned;
- and
- c. fastening means for securing and locking said rotary circuit to a circuit board having slits therein.
