268  DF  TRANSFORMERS AND INDUCTORS WITH INTEGRAL SWITCH, CAPACITOR, OR LOCK (E.G., IGNITION COIL) {2}
270.~ With capacitor element


DEFINITION

Classification: 361/270

With capacitor element:

(under subclass 268) Subject matter comprising a transformer or inductive reactor structurally combined with a capacitor.

(1) Note. If the combined capacitor constitutes an electric or magnetic shield, classification is not herein but rather in Class 336, Inductor Devices, subclasses 87+.

(2) Note. The capacitor may be provided to protect the switch contacts of an ignition coil.

174, Electricity: Conductors and Insulators,

32+, for anti-inductive structures utilized with electrical conductors. Note, particularly indented subclasses 35+ for screened or shielded conductors. 333, Wave Transmission Lines and Networks, appropriate subclasses for electric filter devices comprising the combination of a transformer or inductive reactor and a capacitor.

334, Tuners,

59+, for a switch operated tuner which is of the tuned transformer type, the transformer usually being combined with a lumped capacitor, and subclasses 61+ for tuners having mutual inductance variable means which may be a transformer circuit.

336, Inductor Devices, and see (1) Note above.
