DEFINITION

Classification: 337/351

(under subclass 334) Subject matter including significant details of means whereby contact opening or closing is accomplished by the operation of a mechanical device moving in a rotary or oscillatory manner in a single plane for

example, circulatory motion in a horizontal plane with a reversal of direction.

(1) Note. For other rotary or oscillatory mechanisms used in devices in this class, see the subclasses listed under SEARCH THIS CLASS, SUBCLASS in subclass 10.
