(under subclass 130) Devices having an electrical switch supported by the discharge device structure.
SEE OR SEARCH THIS CLASS, SUBCLASS:
2, for consumable-electrode discharge devices provided with an electric switch for shifting the current to another electrode or to another discharge device or lamp when the consumable electrode has been consumed or fails to maintain the discharge.
11, and 17 and indented subclasses, for consumable-electrode discharge devices provided with an electric switch to either open the circuit or to close a shunt circuit about the discharge device when the consumable electrode has been consumed or fails to maintain the discharge.
24, for consumable-electrode discharge devices provided with an electric switch for controlling the operation of the feed regulating mechanism so that the electrodes will be repeatedly separated and brought into physical contact is made between the electrodes so that the discharge is started.
63, for consumable-electrode discharge device systems having the feed regulating mechanism for the discharge device controlled by an electric switch, the operation of the switch being controlled by radiant energy means, such as radiant heat or light.
70, 72, 73 and 74, for consumable-electrode discharge device systems having electric motor operated means for feeding the electrodes of the discharge device, and having the motor circuit controlled by an electric switch. 114, and indented subclasses, for consumable-electrode discharge devices provided with either an electromagnet for moving the electrode or with an electromagnet which controls the operation of the feeding mechanism and having an electric switch which controls the circuit of the electromagnet.
