(under subclass 185) Systems having a periodic switch connected in the current supply circuit so as to periodically interrupt or vary the flow of current to at least one of the load devices.
(1) Note. The periodic switch may be connected in shunt to a load device so as to periodically interrupt or vary the flow of current to the load device by completing a shunt circuit about the load device.

119, and indented subclasses, for systems having automatic means to close a shunt circuit about a load device.
210, and indented subclasses, and the subclasses referred to in the notes to the definitions thereof for other plural load device systems with a periodic switch in the circuit.
