(under subclass 1) Subject matter in which one electrode of one of the devices is electrically connected to an electrode of another of the devices.
(1) Note. Excluded from this subclass and class are structural combinations of a discharge device and an incandescent lamp where the lamp filament is connected either in series or in shunt relation with the discharge electrodes. The excluded devices will be found in Class 315, Electric Lamp and Discharge Devices: Systems, subclasses 46+ where the filament is connected in shunt relation to the discharge electrodes and in subclass 49 where the filament is connected in series relation with the discharge electrodes.
(2) Note. If the connection between the electrodes includes a circuit element such as a resistor, capacitor, inductance, switch, or the like the combination is not classified in this class but in Class 315. The devices in this subclass have a conductive connection but no more.

315, Electric Lamp and Discharge Devices: Systems, (see (1) Note) above, and
3+, 32+, 35+, 64+ for the structural combination of a plurality of discharge devices, or lamps, or a discharge device and a lamp where the structural combination includes a circuit element (e.g., switch, impedance, etc..), connected between electrodes of different ones of such devices. See the notes to subclass 1 for the subclasses which provide for the different types of devices.
