Abstract
A fuseholder with a reject spring which will only accept a ferrule type fuse with an annular groove in the ferrule at one end. The reject member is a reinforcing spring located externally of the fuse clip on the fuseholder and has locking or control members integrally connected to abutments extending through complimentary openings in the sides of the fuse clip. The arms of the spring are connected together in a manner to control lateral movement of the fuse clip within a predetermined distance and also controls lateral movement of the abutments to respectively accept only the groove of a ferrule type fuse when moved outwardly. The reinforcing spring with the reject abutments finds use on fuseholders having no or very low barriers.
