Abstract: A moisture and waterproof seal for a fuse is provided while allowing selectively for fuse visibility enhancing non-breakability, and improved resistance against moisture ingress. The fuse holder includes flexible molded members which are formed with lips towards the ends remote to the fuse ends thereby allowing the lips to engage and envelope the fuse sealing against moisture. A cuff and groove formation leading the lips provides enhanced sealing of the molded parts. The members can be moved between a position exposing the fuse for visibility and the sealing position enclosing the fuse against breakage. Internal to the molded members are yieldable clips for engaging the end ferrules of the fuse.

Abstract: Two spaced support members support a shaft horizontal in partial lower bearing journal surfaces. A retractable pin is positioned above the shaft at each support member to retain the shaft in the journal surfaces. A shelf at each journal surface in front of the pins provides for loading and unloading of the shaft. A flat locking surface fixed to rotate with the shaft and a mating engagable locking member prevent rotation of the shaft.

Abstract: A locking device having a partial bearing surface formed by a shaft cradle. A restraining enclosure is formed by the shaft cradle and a slidably reciprocating detent having a recess therein, the detent being urged to form said restraining enclosure by a tension means.
