An operating mechanism for a toggle switch handle includes a bar that is movably mounted along its longitudinal axis, and a roller head mounted at one end of the bar. The roller head includes two axes for rolls. The first roll of the rolls is provided for turning on the toggle switch handle depending on a movement of the bar, and a second roll of the rolls is provided for rolling over a plate and blocking a rotation of the bar around its longitudinal axis.

A transfer assembly is for a switching assembly mounted in an electrical enclosure. The switching assembly has an electrical switching apparatus, a shaft, and a handle member coupled to the shaft. The electrical switching apparatus is structured to move between an ON position and an OFF position. The transfer assembly includes a body structured to be coupled to the electrical switching apparatus, and a cam assembly structured to move between a FIRST position and a SECOND position. The cam assembly includes a rotary member coupled to the body and structured to be coupled to the shaft, and a driving member cooperable with the rotary member. When the cam assembly moves between the FIRST position and the SECOND position, the driving member drives the electrical switching apparatus between the ON position and the OFF position.

An interlock for a circuit breaker having a first circuit breaker switch and a second circuit breaker switch. The interlock includes a first actuator movably associated with the first circuit breaker switch, a first limiter plate and a first handle securely associated with the first actuator and the first limiter plate. The interlock further includes a second actuator movably associated with the second circuit breaker switch, a second limiter plate, and a second handle securely associated with the second actuator and the second limiter plate. The first limiter plate and second limiter plates are configurable between a first configuration and a second configuration. When the first plate is in the second configuration, the second plate is non-movably configured in the first configuration, and when the second plate is in the second configuration, the first plate is non-movably configured in the first configuration.

Circuit breakers with a rotary handle attached to an inwardly oriented shaft that connects to a gear assembly that translates rotational input to linear input also include a trip assist spring in communication with the rack gear so that, in operation, the trip assist spring applies a force to the operator slider and forces the handle to a consistent trip position.

An electric switch comprising a mechanism module and a contact module, the contact module comprising a base element, a cover element, fixed contacts and a rotary roll for receiving moving contacts, the mechanism module comprising a base element, a cover element, a front pipeshaft for controlling the switch from front, an inner pipeshaft for controlling the switch from side end, the pipeshafts being engaged to each other by teeth to form a gear for transferring a moment from the front pipeshaft to the inner pipeshaft, a lever for transferring a moment to the roll, the lever arranged to receive the inner pipeshaft, the inner pipeshaft and the lever being rotatable engaged with each other, and main springs for giving a rotational moment for the lever and being connected of first ends to the base element and the mains springs being connected to the lever of their second ends.

A transfer assembly is for a switching assembly of an electrical enclosure. The switching assembly includes an electrical switching apparatus having an operating handle structured to move from an OFF position to an ON position. The transfer assembly includes a driving handle; a first shaft member coupled to the driving handle; a second shaft member structured to be coupled to the operating handle; and a transmission assembly having a first component and a second component, the first component being coupled to the first shaft member, the second component being coupled to the second shaft member. The transfer assembly is structured to move from a FIRST position to a SECOND position. When the transfer assembly moves from the FIRST position to the SECOND position, the first component drives the second component, thereby causing the second shaft member to move the operating handle from the OFF position to the ON position.

An actuator assembly for actuating electrical switches housed in an electrical enclosure is disclosed. The assembly includes at least one handle assembly including a handle positioned above a cover of the enclosure, a trip bracket positioned below the cover and a shaft connecting the handle to the trip bracket. At least one slider actuator is slidably mounted over the electrical switch and coupled to a toggle of the electrical switch. The slider actuator has a drive link which is adapted to be engaged with the trip bracket such that rotation of the handle causes the drive link to slide which in turn causes a linear movement of the slider actuator to toggle the electrical switch. The use of the slider actuator allows a higher density of electrical switches to be stacked inside the enclosure.

A lockout, tagout (LOTO) device and associated implementation method for a switchable energy isolation device are provided. The isolation device includes first and second electrical terminal members and a slideable linkage disposed and in electrical communication therebetween for switching the electrical terminal members between isolated and non-isolated states. The LOTO device includes a cover member configured to extend over the terminal members and the linkage, and a fastener member coupled to the cover member. The fastener member is configured to engage the first or second electrical terminal member to secure the cover member to the isolation device. A tagging member is configured to engage the fastener member and a securing member engaged with the cover member, upon the cover member being secured to the isolation device, to prevent the fastener member from disengaging the first or second electrical terminal member without the tagging member disengaging the fastener member.

An electronic switching device includes a housing with at least one housing door, a lockable rotary handle rotatable at least between an ON position and an OFF position, a handle locking device for locking the rotary handle at least in the OFF position when engaged, and a POFF device for preventing the rotary handle to be rotated and/or fixed in OFF position when activated. The electronic switching device further includes a locking coulisse, movably arranged at the electronic switching device and arrangeable in at least a first position, a second position and a third positions with respect to the housing of the electronic switching device. The locking coulisse is configured for allowing an engagement of the handle locking device and the POFF device in the first position, locking the housing door in the second position and blocking the activation of the handle locking device in the third position.
