DEFINITION

Classification: 200/462

Tension spring (e.g., pull force):

(under subclass 405) Subject matter including a spring which is used to exert a pulling force to cause the quick abrupt motion of the contacts.

(1) Note. Normally the contacts are pivoted and directly connected to the spring although there may be a linkage between the snapped element and the contacts.

SEE OR SEARCH THIS CLASS, SUBCLASS:

449, for similar snap devices normally using a pivoted snapped member with a linkage to cause the contacts to reciprocate in a straight line motion.
