DEFINITION

Classification: 335/76

(under subclass 71) Subject matter wherein the contact actuating structure includes, mechanical energy storage means whereby the movable contact or contacts are actuated to or from the closed position, the energy storage taking place through the agency of a motor wound spring or other kinetic energy device. The energy storage means may actuate the contacts through mechanical gearing which comprises in itself all the elements of a spring motor; for example, a clock movement actuated switch is considered a motor driven switch for classification here provided the spring is recharged by electric motor means. The storage means may also consist of inertia means released by a motor and transmitting energy via the force of gravity.
