TRANSFORMERS AND INDUCTORS WITH INTEGRAL SWITCH, CAPACITOR,OR LOCK (E.G., IGNITION COIL):
(under the class definition) Subject matter comprising a structural combination of a transformer or inductor with a switch, capacitor or a lock.
(1) Note. If the switch is solely for the purpose of tap changing on the transformer or inductor device, classification is not herein but rather in the appropriate subclass of Class 336.
(2) Note. This subclass relates, for example, to ignition coils having integral vibrating switches.
