DEFINITION

Classification: 200/472

Detent function performed by spring biased contact (e.g., knife blade):

(under subclass 471) Subject matter wherein the stationary contact acts as a spring biased detent, restraining the moving contact until a spring connected to the moving contact, overcomes the detent spring force allowing the moving contact to quickly separate.

(1) Note. Included in this subclass are double throw switches which snap away from both contacts. These are considered single snap devices because the contacts do not snap closed.
