DEFINITION

Classification: 337/147

(under subclass 143) Subject matter wherein the mechanical contact control structure comprises means whereby a movable contact, or contacts, may be operated from a first position to a second position quickly by a snap action. This is usually accomplished by a spring connection between an operator and a contact carrier so arranged that the initial movement of the operator places the spring under tension whereby upon release of a holding means the movable contact is snapped from one position to another.
