Abstract
The disclosed switching fusible apparatus includes a fuse-holding device receivable in a receptacle and rotatable to "ON", "OFF" and "RELEASE" positions. The fuse-holding device comprises a fuse holder for containing a larger fuse and it may comprise the fuse holder containing an adapter which, in turn, contains a smaller fuse. A slot in the exposed end of the fuse holder receives a screw-driver for selectively turning the fuse-holding device when tool-operable apparatus is required, or a knob is interlocked with the slot in high-profile apparatus. Contact is made to each end cap of each fuse in the "ON" position of the fuse-holding device by a contact tab that is not significantly yielding per se but which is rendered prominently resilient by oppositely extending resilient torsion supports extending along the elongated fuse-holding device.
