DEFINITION

Classification: 337/186

(under subclass 142) Subject matter wherein the fusible electrothermally responsive circuit opening or closing means is specifically described as combined with significant protective housing, casing or support means. The subject matter to be found here comprises an entire switch assembly in combination with unique protective or support means especially adapted for the protection or support of fuse type switching or circuit interrupting devices under the subclass 142 definition. The housing, casing or support means found here form no part of the fuse structure, per se, but are adapted to interchangeably receive fuse devices and operatively maintain them in position until bodily removed.

(1) Note. For other housing, casing or support means for devices of this class, see the subclasses listed under SEARCH THIS CLASS, SUBCLASS in subclass 20.
