Definitions
- An electrical switch of a type suitable for use as an open fuse cutout is provided with a pair of fixed contacts of a metal, such as aluminum alloy, mounted at opposite ends of a pivotally mounted switch blade, or rigidly supported fuse link, that is adapted to be pivoted on one of the fixed contacts and moved into engagement with the other fixed contact.
- the contacts mounted on opposite ends of the elongated insulating member are characterized by having integrally formed therewith electrical line terminals that are adapted to cooperate with a clamping means to secure a power line conductor to each of said line terminals.

Abstract
AN ELECTRICAL SWITCH OF A TYPE SUITABLE FOR USE AS AN OPEN FUSE CUTOUT IS PROVIDED WITH A PAIR OF FIXED CONTACTS OF A METAL, SUCH AS ALUMINUM ALLOY, MOUNTED AT OPPOSITE ENDS OF A PIVOTALLY MOUNTED SWITCH BLADE, OR RIGIDLY SUPPORTED FUSE LINK, THAT IS ADAPTED TO BE PIVOTED ON ONE OF THE FIXED CONTACTS AND MOVED INTO ENGAGEMENT WITH THE OTHER FIXED CONTACT. THE CONTACTS MOUNTED ON OPPOSITE ENDS OF THE ELONGATED INSULATING MEMBER ARE CHARACTERIZED BY HAVING INTEGRALLY FORMED THEREWITH ELEC-
TRICAL LINE TERMINALS THAT ARE ADAPTED TO COOPERATE WITH A CLAMPING MEANS TO SECURE A POWER LINE CONDUCTOR TO EACH OF SAID LINE TERMINALS. BY FORMING THE LINE TERMINALS INTEGRALLY WITH THE CONTACTS, THE RISK OF GALVANIC CORROSION BETWEEN THESE RESPECTIVE ELEMENTS IS SUBSTANTIALLY DIMINISHED RELATIVE TO PRIOR ART CONTACT AND LINE-TERMINAL ASSEMBLIES.

Int. Cl. H01h 31/00 US. Cl. 20048 R 2 Sheets Drawing. 12 Pages Specification An electrical switch of a type suitable for use as an open fuse cutout is provided with a pair of fixed contacts of a metal, such as aluminum alloy, mounted at opposite ends of a pivotally mounted switch blade, or rigidly supported fuse link, that is adapted to be pivoted on one of the fixed contacts and moved into engagement with the other fixed contact. The contacts mounted on opposite ends of the elongated insulating member are characterized by having integrally formed therewith electrical line terminals that are adapted to cooperate with a clamping means to secure a power line conductor to each of said line terminals. By forming the line terminals integrally with the contacts, the risk of galvanic corrosion between these respective elements is substantially diminished relative to prior art contact and line-terminal assemblies.
