.~ Movable contact adjustable over length of inductor {1}
73
.~.~ With capacitor-type contact
DEFINITION
Classification: 334/73
(under subclass 72) Subject matter in which the movable contact element does not come into direct electrical contact with the inductor coil but is capacitively coupled thereto.
(1) Note. Usually there is an insulative coating between the movable contact and the coil windings thus preventing the contact from making direct electrical contact with the coil. The contact surface usually serves as one plate of a capacitor with the coil of the inductor serving as the second capacitor plate. Electrical energy is transferred between these capacitor plates.
