DEFINITION

Classification: 337/356

(under subclass 334) Subject matter wherein the mechanical structure includes significant details of operating means whereby the contacts may be retained in a first condition by a latch or detent capable of being tripped by a thermal responsive device. The contacts are usually held latched in a circuit closing condition and tripped to open position.

(1) Note. For other latch mechanisms used in devices of this class, see the subclasses listed under SEARCH THIS CLASS, SUBCLASS in subclass 46.
