An operating attachment for arrangement on a predefinable switching device and for operating a pivotable switching device toggle of the switching device includes: a one-sided open housing positionable on the switching device; a rotatable shaft having a rotation axis; a manual operating part, the manual operating part being situated on the rotatable shaft; a switch-on projection for pivoting the switching device toggle in a first pivot direction, the switch-on projection being situated on the rotatable shaft; a switch-off projection for pivoting the switching device toggle in a second pivot direction opposite the first pivot direction, the switch-off projection being situated on the rotatable shaft; and a housing stop for contacting a stop edge of the switch-off projection, the housing stop being situated in the one-sided open housing. The switch-off projection yields resiliently such that the switch-off projection is bent for contact with the housing stop.

The construction comprises a rotary handle with a first pivot axis, a locking latch with a second pivot axis, a fixed bottom ring, a locking pin movable with the locking latch between a first position in which the rotary handle can be turned in relation to the bottom ring and a second position in which the locking pin prevents turning of the rotary handle in relation to the bottom ring, a shaft adapter rotationally movable against a spring force in relation to the rotary handle. The shaft adapter comprises a protrusion having a locking member which locks the locking pin into the first position when the torsional moment acting on the rotary handle exceeds the spring force acting on the shaft adapter causing a limited rotational movement of the shaft adapter in relation to the rotary handle.

A switching operation mechanism to a molded case circuit breaker, including at least one operating handle, which is movable in a rotatable trajectory, said switching operation mechanism including at least one external rotary handle, at least one operation member and at least one movement transmission means, the said operation member being capable of moving in rotating trajectory in equivalent direction to the movement in rotating trajectory of the handle for operating the circuit breaker in molded case, arranged inside a housing including a laterally bipartite body, reaching an efficient movement transfer, requiring less mechanical effort of proportional operation of the user on the external rotary handle, wherein it is possible to maintain an external rotary handle, of great dimensions proportional to the assembled assembly, within the general perimeter of the molded case circuit breaker.

An operator for an electrical switching apparatus includes an actuator configured to be grasped by a user. A linkage is attached to the actuator at a first end of the linkage and configured for extending through an enclosure housing the electrical switching apparatus. An engagement assembly is attached to the linkage at a second end of the linkage such that when the operator is mounted to the enclosure movement of the actuator outside of the enclosure causes movement of the engagement assembly inside the enclosure. The engagement assembly includes an extension arm attached to the linkage and an attachment member attached to the extension arm. The attachment member is configured to engage a toggle of the electrical switching apparatus in the enclosure to move the toggle between at least two positions.

A transfer assembly is for an electrical switching apparatus. The electrical switching apparatus has a first housing, separable contacts internal the first housing, and an operating handle having an ON position and an OFF position. The transfer assembly includes a rotary handle, a number of transfer components each structured to cooperate with the rotary handle, one of the transfer components being structured to engage the operating handle in order to allow the rotary handle to move the operating handle between the ON position and the OFF position, and a support assembly. The support assembly includes a second housing and a support member coupled to and located internal with respect to the second housing, the second housing being structured to be coupled to the first housing, the rotary handle being coupled to the second housing. Each of the transfer components is coupled to the support member.

An electrical disconnect switch including an over-rotation protective feature to protect the load switch from damage is disclosed. The electrical disconnect switch may include an enclosure, a load switch, and a handle assembly coupled to the load switch. The disconnect switch may include a detent between the handle assembly and the load switch so that during excessive rotation or torqueing the handle assembly is permitted to decouple or break-away from the load switch to prevent excessive stress from being transferred to the load switch and thus prevent any damage to the load switch.

An engageable drive engageable operating mechanism for converting a movement of a linear translation operating handle to a rotating handle movement relative to the operative front face engageable with a molded-case circuit breaker. The mechanism includes an external rotating adapter external rotating operating member or alternatively an engageable drive engageable operating mechanism incorporating a handle assembly external rotating operating member, interchangeable with each other; and a gear, a support movable movement-converting support including a rack portion, and a structural support base, wherein the structural support base includes a built-in side opening chamber.
