ABSTRACT:
A variable electronic component for use in a subminiature electronic circuit and adapted to provide a desired range of impedance characteristics. The variable electronic component may take the form of a variable trimmer capacitor, a variable resistor, and the like constructed to include an eccentric whose rotational motion imparts reciprocal movement to an impedance varying member. The eccentric is operative by engagement with an implement such as a screwdriver and the like.
