A key structure includes a base plate, a key cap, a supporting member, a link member, and a buffer member. The base plate includes a body portion and a protrusion portion protruding upward from the body portion. The body portion has an accommodating hole, the accommodating hole corresponds to the protrusion portion, and the protrusion portion has an opening. The key cap is disposed above the base plate. The supporting member is disposed between the key cap and the base plate. The link member includes a main body portion and an end portion. The main body portion is pivotally connected to the key cap, and the end portion is disposed at the opening of the protrusion portion. The buffer member is located below the end portion, and the end portion leans against the buffer member.

Handle assemblies for circuit breakers are disclosed. One illustrative handle assembly includes a housing defining a first aperture, a seal extending around a perimeter of the first aperture, a handle extending outwardly through the first aperture and pivotable about a pivot axis located within the housing, a shroud coupled to the handle to move therewith and located at least partially within the housing, and a biasing member connected to the handle and to the shroud. The shroud includes an outer surface that faces the seal, and the biasing member biases the outer surface into continuous engagement with the seal throughout an entire pivotable range of the handle.

A remote drive with a support element for a top-hat-rail mounting. Opposing actuators disposed on the support element alternatingly act on a displaceably mounted slider by rod-shaped anchors. A slider passage receives a first lever arm of a rocker lever pivotable about a rotational axis parallel to the top hat rail length and nearly passes through a rotational point of a shift lever of a switching device. A carrier rail on a second lever arm is parallel to the top hat rail length, the shift lever engaging the carrier rail to the side of the second lever arm. When the slider is displaced, the rocker lever flips simultaneously activate the shift lever. In a remote drive assembly, two remote drives are disposed adjacent to one another on a top hat rail with a locking mechanism. Alternatively, individually controlled actuators act on first and second legs of a T-shaped rocker switch.

The disclosure provides a key assembly, including: a baseplate, having a top surface and a recess groove recessed from the top surface, in which the recess groove is a blind hole; a hook, disposed on the baseplate, and extending upward from the top surface to form a hole between the hook and the top surface, in which an orthographic projection range of the hook and an orthographic projection range of the recess groove do not overlap each other; a key cap, disposed on the baseplate; an elastic member, disposed between the key cap and the baseplate; a link bar, connecting the key cap and the baseplate, in which the link bar has an extension portion passing through the hole; and a membrane, disposed on the top surface of the baseplate, in which the membrane covers at least part of the recess groove, and the extension portion abuts the membrane.
