ABSTRACT:
A switch, for an electrical transmission line, can be used as a vertically mounted cut out or as an in-line switch. The switch has an insulator, mounting bars at either end, and a first and second brackets extending from the mounting bars. Brackets are configured to receive a fuse element, which can be of known construction. A first bracket includes a pair of bracket elements that defines slots for receiving pivot lugs of the fuse element. To enable the switch to be used either vertically as a cut out or horizontally as an in-line switch, the bracket elements are moveably, preferably rotatably, mounted to the first bracket. The bracket elements can then be located so that the slot is always at least partially directed upwardly. Then, for either use, the fuse element will always be retained by its pivot lugs in the slot. To enable the switch to be mounted as an in-line switch, the insulator can be provided with a relatively narrow central portion to its body and a removable clamp. The clamp would be used for such vertical mounting, and would be removed for use as an in-line switch.
