DEFINITION

Classification: 314/15

(under subclass 11) Subject matter wherein the switch which completes the shunt circuit is an electroresponsive switch operated by means of voltage and/or current changes in the circuit of the discharge device.

(1) Note. Continue the search in subclasses 13 and 14 of this class.

(2) Note. This subclass does not include discharge devices having the switch operated by means of a cam, projection, detent or other means carried by the electrode rod or electrode supporting means, or some other part of the discharge device which moves in relation to the movement of the electrode, so that the switch is operated only when the electrode has been moved to a predetermined position. Discharge devices having only this type of shunt switch operation are in subclass 11 or in indented subclasses 12 and 13.
