ABSTRACT:
A variable electronic component in the nature of a small sealed capacitor includes a pair of free floating dielectric plates disposed overlying a conductive body which is displaceable therebetween along a linear path. The conductive body is brought into varying degrees of overlapping registration with a conductive layer on the dielectric plates to vary the impedance characteristics of the capacitor between minimum and maximum values.
