DEFINITION

Classification: 335/68

(under subclass 2) Subject matter wherein the electromagnetic switch operating mechanism comprises or includes an electric motor or the combination of electromagnetic means with at least one rotating motor means, in addition to the electromagnetic means, whereby the main contacts are caused to be operated to either the open or closed position. The additional motor means may consist of a spring motor

operatively connected with an electromagnet.

(1) Note. The electric motor structure to be found in this and the indented subclasses may be either of the direct current or alternating current variety. No effort has been made to distinguish between A.C. and D.C. in this subclass, the motor being merely the significant means for driving a particular class of switch. For alternating current switches of general utility without motor means the search will be in subclasses 99+ below.

30, for automatic circuit breakers with mechanical motor controlled trip or latch.

65, for switches with motor controlled delay means.

118, for automatically actuated multiple contact switches of the telephone type which are motor driven. SEE OR SEARCH CLASS

185, Motors: Spring, Weight, or Animal Powered, for mechanical motors, per se, of the weight or spring actuated type.

200, Electricity: Circuit Makers and Breakers,

17+, for nonmagnetically operated multiple circuit control devices with motor operating means, subclasses 19.03+, 19.07+ and 19.18+ for rotary periodic switches, subclass 48 for significant structure comprising motor and related mechanisms rotatable to operate high potential electric switches, subclass 80 for centrifugal switches which may be motor driven and subclass 155 for rotating mechanical switches.

246, Railway Switches and Signals,

99, for automatic railway block signalling systems which are clock work controlled, subclasses 221+ for electric motor systems for signal switch actuation, e.g., see also subclasses 102, 103 and 263 for mechanical motor systems.
