DEFINITION

Classification: 200/453

Compression spring (e.g., push force):

(under subclass 405) Subject matter wherein the snapping action is caused by a resilient member (e.g., spring) prestressed (i.e., compressed) by colinear, opposed forces.

(1) Note. Included herein are one piece leaf spring elements which are shaped to have legs in both compression and tension. The nature of the leg under compression governs classification.

450, for similar snap devices using a linkage to cause the oscillated snap element to drive the contact in a reciprocating straight line motion.
