DEFINITION

Classification: 315/214

(under subclass 212) Systems having a periodic switch (in addition to the distributor switch means) in the primary circuit of the transformer so as to periodically interrupt the primary circuit, the distributor type periodic switch means being in the secondary circuit of the transformer.

SEE OR SEARCH THIS CLASS, SUBCLASS:

213, for plural load device systems under subclass 212, where a distribution type periodic switch is included in the primary circuits of the transformer.

215, for additional periodic switches in circuits having no transformer.

222, for single load device systems under subclass 209 wherein there is a transformer in the supply circuit of the load device, and the primary and secondary circuits are periodically interrupted by periodic switch means.
