A safety switch includes a housing including first and second compartments that are separated by a barrier, a switch mechanism in the first compartment, one or more fuse holders in the second compartment, a first door connected to the housing and covering the first compartment, a second door connected to the housing, a handle connected to the switch mechanism, and a locking mechanism operatively connected to the handle. The handle is movable between an off position and an on position. The locking mechanism configured such that: the second door is locked in a closed position when the handle is in the on position; the second door is movable from the closed position to an open position to expose the second compartment when the handle is in the off position; and the handle is locked in the off position when the second door is in the open position.

Safety switch having interlocking handle and door

An electrical switch assembly includes a first contact supported for movement into and out of electrical connection with a second contact. A cam assembly is configured to deflect a spring into a stressed condition, and to move the first contact into electrical connection with the second contact under a bias of the spring upon return deflection of the spring from the stressed condition. A motor has an output member. A linkage interconnects the output member with the cam assembly to deflect the spring into the stressed condition in response to movement of the output member.

Bolted pressure switch motor arrangement

An interlock assembly for a safety switch includes a linkage. A first end of the linkage is coupled to the operating handle of the safety switch in order that moving the operating handle results in a corresponding movement of the second end of the linkage into and out of an aperture in a bracket member. The bracket member is movably coupled to the safety switch enclosure by a fastening mechanism. When the cover of the safety switch is disposed in its open position, the bracket member is disposed in a first position preventing the second end of the linkage from entering the aperture and resisting undesired movement of the operating handle. When the cover is closed position, the bracket member is moved to a second position corresponding to the second end of the linkage being receivable by the aperture in order that the operating handle is movable.

Electrical switching apparatus and interlock assembly therefor

An enclosed switching apparatus includes an enclosure and a primary power supply disconnect mounted in the enclosure. The primary power supply disconnect has first and second terminals, the first terminals are electrically connectable to a primary power source and the second terminals are electrically connectable to a load. An auxiliary power supply unit includes an auxiliary power supply disconnect having third and fourth terminals. The third terminals are electrically connectable to the primary power source. A transformer has fifth and sixth terminals, the fifth terminals are electrically connected to the fourth terminals of the auxiliary power supply disconnect. An auxiliary fusible element has seventh and eighth terminals, the seventh terminal is electrically connected to one of the sixth terminals of the transformer. A receptacle has ninth terminals thereon. One of the ninth terminals is electrically connected to the eighth terminal of the auxiliary fusible element.

Safety switch with integrated auxiliary power supply and convenience receptacle

An electrical connector assembly is provided for an electrical switching apparatus including an enclosure, separable contacts housed by the enclosure, and an operating mechanism structured to open and close the separable contacts. The enclosure has a back panel, sidewalls extending outwardly from the back panel, an exterior and an interior having a plurality of compartments. A first compartment houses the separable contacts and includes a first cover. A second compartment is disposed adjacent the first compartment and includes a second cover. The electrical connector assembly includes a plate member disposed between the first and second compartments, and a plurality of electrical connectors coupled to the plate member and being substantially disposed within the second compartment. The electrical connectors are structured to be electrically connected to the separable contacts, and are substantially inaccessible when the second compartment is covered by the second cover.

Safety switch, and enclosure and electrical connector assembly therefor

An interlock assembly is for locking the operating assembly of a safety switch when the cover thereof is open or removed. The safety switch includes an enclosure with the cover and side walls. The operating assembly includes a bracket and a spring-toggle mechanism with a spring-biased drive link having an arm. An operating handle, which is coupled to the spring-biased drive link, operates the operating assembly. The interlock assembly includes a pivotal lever having a catch and a sensing portion. A pivot receives a blind rivet and pivotally couples the pivotal lever to the side wall. A torsion spring biases the pivotal lever toward engaging the arm of the spring-biased drive link in order that the catch engages and locks the arm when the cover of the enclosure is open. The sensing portion is engaged and pivoted by the cover when it is closed.
