.~ With longitudinally expansible solid element {7}
383
.~.~ With plural contacts or external circuit completion means
DEFINITION
Classification: 337/383
(under subclass 382) Subject matter including significant details of at least two or more contact pairs operative in such a manner that at least two or more separate and distinct electrical circuits may be controlled by the longitudinally expansible element. One of the plurality of contacts may be common to more than a single contact pail.
