DEFINITION

Classification: 337/137

(under subclass 123) Subject matter including significant details of contact structure, composition of material or arrangement peculiarly adapted to be or specifically recited as, operative through the agency of at least one longitudinally expansive electrothermal current responsive element. The structure usually comprises adjustment screw or other means whereby the relative position of the contacts may be varied automatically or at the will of an operator.

(1) Note. For contact structure or contact composition of material used in devices of this class, see the subclasses listed under SEARCH THIS CLASS, SUBCLASS in subclass 26.

(2) Note. Consult the classes and subclasses listed under the search notes to subclass 109, above, for a complete listing of the classes containing similar subject matter.

SEE OR SEARCH THIS CLASS, SUBCLASS:

109, for particular contact structure in electrothermally responsive bimetallic element actuated switches.

399+, for significant contact structure for use in similar devices utilizing thermally responsive solids. See (1) Note above.
