A bridge joint cover assembly for a busway bridge joint, the assembly comprising at least one cover plate having an opening and a viewing plate including infrared (IR) material. The IR material is aligned with the opening of the cover plate.

A veneer for a wall-mounted keypad may include indicia that are laser cut therethrough and that are representative of functions that may be performed by the keypad. The veneer may include a recess that extends into an inner surface of the veneer, proximate to the indicia. The recess may be shaped such that a perceived aesthetic of an outer surface of the veneer is preserved during formation of the indicia. The recess may for example have an organic shape defined by a curved outer perimeter that does not define any corners.

An isolating switch for a circuit includes: a switching mechanism movable between an open position in which the circuit is open and a closed position in which the circuit is closed; and a housing. The housing includes: a first housing component coupled to and enclosing the switching mechanism; a second housing component coupled to the switching mechanism and movable with respect to the first housing component to move the switching mechanism between the open position and the closed position; at least one aperture arranged in one of the first or second housing components; and at least one test point electrically connected to the circuit and arranged in an other of the first or second housing components. The second housing component is movable with respect to the first housing component between at least: a first relative position in which the switching mechanism is in the closed position.

The invention relates to a disconnecting device for a surge arrester which is accommodated by a support body, and wherein plug contacts which are connected to at least one arrester element of the surge arrester extend from the support body. The invention further comprises a switching tongue which is connected at a first end to the arrester element via a thermal separating point and with a second end to one of the plug contacts. Furthermore, a spring-preloaded insulating disconnecting bracket which is pivotably mounted on the support body is provided, the spring preload acting on the thermal separating point via the switching tongue. According to the invention, the switching tongue is configured as a straight-surface, elongated, metallic, resiliently elastic disconnecting strip having a rectangular cross-section.

In accordance with certain embodiments, an improved switching mechanism and related components are provided. In accordance with one embodiment, an apparatus can include a switching mechanism rated to switch at least 27 kilovolts; a housing to house the switching mechanism; an isolation point of the switching mechanism visible from outside the housing to visibly exhibit a physical open-circuit by the switching mechanism; wherein the isolation point is electrically insulated without using SF.sub.6 gas during operation.
