Definition

This class is restricted to the structure of electric current switching devices or relays of general application for closing or opening electrical circuits which devices are magnetically operated or to magnet structure, per se, either electromagnets or permanent magnets, adapted for use as a source of magnetic flux for performing external work.

The devices classified in this class are for the most part of the electromagnetic type utilizing magnetic cores and armatures. However, included also are devices of the electrodynamic type wherein mutually coupled conductors are caused to move relative to each other by the interaction of the magnetic fields produced by the flow of electric currents in the conductors.

Combinations of magnetically actuated circuit makers and breakers or work magnets and electromagnets with electrical connector plugs, sockets or other special type housings or casings are in this class.

Electrical systems or circuits which include the magnetically controlled switches or relays or work magnet and electromagnet structures comprising the subject matter of this class, are excluded from this class. These systems or circuits are classified in the various electrical or art classes depending upon the type of electrical system or apparatus controlled.

This class also includes subcombinations of magnetically actuated switches and relays classified in this class and which are either claimed as used in a magnetically actuated switch or relay or which are by disclosure peculiar to such use.
