An enclosed switch, a bus plug or a panelboard switch with means to lock them in an OFF position are provided. An enclosed switch comprises an operating handle with a first hole situated at a distal end and an enclosure including a cover. The operating handle is disposed external to the enclosure. The cover having a flange including a tab formed with a second hole that is configured to be aligned with the first hole of the operating handle in order to lock the enclosed switch in an OFF position without the use of a handle guard.

Locking an enclosed switch, a bus plug or a panelboard switch

An electrical switching assembly. The electrical switching assembly includes an integral handle and rotor unit including an integral rotor portion and a handle portion. The rotor portion is configured to receive one or more conductors and is configured to be received in a line base. The integral handle and rotor unit includes the handle portion and the rotor portion in a one-piece assembly and the integral handle and rotor unit is molded as a single unit and formed from a single rigid insulating material.

Switching assemblies with integral handle and rotor and methods of assembly

A switch box mechanism of an enclosed switch assembly. The switch box mechanism includes a swivel catch having an elongated body, a pivot configured to allow the swivel catch to rotate relative to an enclosure, and a catch end including a catch configured to engage with an enclosure lid, and a slide feature formed in the elongated body, a rod configured to couple to a switch engagement member that is configured to engage with a rotor of a line base assembly, the rod having a slide portion slidably engaged with the slide feature, and a spring configured to bias the swivel catch. Enclosed switch assemblies and switch subassemblies including the switch box mechanism, and methods of operating enclosed switch assemblies are disclosed, as are other aspects.

Swivel catch apparatus, enclosed switch assemblies, and operational methods thereof

An electrical switching assembly. The electrical switching assembly includes an integral handle and rotor unit including an integral rotor portion and a handle portion. The rotor portion is configured to receive one or more conductors and is configured to be received in a line base. Assembly methods for electrical switching assemblies are provided, as are other aspects.

A device is provided for use with an electrical apparatus. The device comprises a wiring lug having a side and a base configured to receive a mounting screw. The wiring lug is configured to connect with a wire. The device further comprises a shaped spring configured to apply a force to a fuse for maintaining an electrical connection between the fuse and the wiring lug thus eliminating a separate electrical bus part that in a typical installation would pass a current from a conductive fuse clip to the wiring lug. The shaped spring provides a fuse clip with one side defined by the shaped spring and other side defined by the side of the wiring lug to contact a ferrule on the fuse or contact a blade extending from the ferrule on the fuse.

Wire nut (lug) fuse holder combination

A non-fusible switch assembly including a line base assembly is disclosed. Line base assembly includes a load bus connector assembly with single-piece lug body, first and second load lugs formed in the lug body, and load-side sliding nuts slidably received in first and second load-side slide features, and load-side stationary contacts positioned directly underneath of the first and second load lugs within a projected footprint of the lug body. Line base assemblies, load lug connector assemblies and methods of operating a line base assembly are provided, as are other aspects.

Non-fusible switch assemblies, line base assemblies, load bus connector assemblies, and operational methods

A fusible switch assembly including a line base assembly and load base assembly is disclosed. Line base assembly includes a low-profile fuse clip assembly and line bus connector assembly with single-piece connector body and sliding nuts. Load base assembly includes a fuse clip and lug assembly having a lug body including a multiple lugs and a fuse clip at least partially formed by the lug body. Line base assemblies, load base assemblies, fuse clip assemblies, line bus connector assemblies, fuse clip and lug assemblies, and methods of operating line base assemblies are provided, as are other aspects.

Fusible switch assemblies, and load base assemblies, line base assemblies, line bus connector assemblies, fuse clip assemblies, fuse clip and lug assemblies, and operational methods thereof

The present invention relates generally to handle stops. More particularly, the invention encompasses a positive handle stop for a switch. The positive handle stop for a switch, such as, a safety switch, prevents the handle of a switch from returning to the shipping position once the switch is turned ON. The invention also includes a shipping position for the inventive handle so as to reduce the size of the packaging need to ship the switch apparatus.
