.~ Capacitor only modified or substituted by switching
DEFINITION
Classification: 334/55
(under subclass 47) Subject matter in which the element or elements substituted by the switching operation consists of a plurality of capacitors.
(1) Note. Subject matter usually found in this subclass consists of an inductor element which is mechanically fixed in the tuned circuit and is connected to a switch which substitutes various capacitors into or out of the circuit to thus vary the resonant frequency of the tuner.
SEE OR SEARCH THIS CLASS, SUBCLASS:
7, for push button and/or lever operated tuners which may be of the type which substitutes one capacitor for another within the tuned circuit.
78+, for tuner units which are tuned by a continuous variable capacitor.
SEE OR SEARCH CLASS 320, Electricity: Battery or Capacitor Charging or Discharging,
166+, for charging or discharging a capacitor, per se.
