3. The combination with a group or number of gas or vapor electric devices, each requiring a starting-current of higher potential than that upon which it is to be operated, of a reactance coil or coils for supplying the starting-current to each device, switches controlling the connections of each device with its own reactance coil or coils, a snap or quickbreak switch having one terminal adapted to be connected to a corresponding terminal of each device, means for connecting the opposite terminal of the snap or quickbreak switch, to the opposite terminal of any selected device, thus forming the shunt upon the reactance coil or coils for that device, and means for operating the snap-switch to break the said shunt by a quick movement.

4. The combination with a group or number of gas or vapor electric devices, each requiring a starting-current of higher potential than that upon which it is to be operated, of

a reactance coil for each device, a shunt across the circuit between each device and its reactance-coil, a snap or quick-break switch having one terminal connected with one side of the said shunt-circuit, means for connecting the opposite side of the snap-switch with any selected device and means for operating the snap-switch whereby the shunt-circuit of the selected device can be broken by a quick movement, thus causing the reactance-coil for that device to start the device.

5. The combination with a group or number of gas or vapor electric devices, each requiring a starting-current of higher potential than that upon which it is to be operated, of a plurality of reactance-coils in series with each device, means for cutting out one or more layers of one of the reactance-coils, a shunt across the circuit between each device and its reactive coil and a snap or quickbreak switch adapted to act upon either shuntcircuit at will.

6. The combination with a group or number of gas or vapor electric devices, each requiring a starting-current of higher potential than that upon which it is to be operated, of an adjustable inductive resistance in series with each device, a shunt across the circuit between each device and its own inductive resistance, and a snap or quick-break switch adapted to act upon either shunt-circuit at will.
