A luminaire (30) or electrical unit for connection to a supporting rail (10) has a contacting element (40, 50, 60), which is introducible into the supporting rail profile (15) and has connection contacts (42, 52, 62) mounted adjustably in order to bear against lines (25) of the busbar (20) in a state in which the contacting element (40, 50, 60) has been inserted into the supporting rail profile (15). The contacting element (40, 50, 60) has at least one contact block (41, 42, 51, 52, 61, 62) with connection contacts (43, 53, 63), which is linearly laterally adjustable between an open position and a contacting position.

A conductor connection terminal, having an insulating material housing, a busbar, a clamping spring and an operating lever which is pivotably received in the insulating material housing over a pivoting range and can be pivoted between an open position and a closed position, wherein the clamping spring has an operating arm which is deflected via a spring driver of the operating lever at least in the open position, characterized in that the operating lever is supported in the open position at a first and a second support point spaced from the first, and that the operating lever is pulled against the first and the second support point by a tensile force of the clamping spring acting on the spring driver from the operating arm.

A spring-clamp terminal block for connecting an electrical conductor, with a bus bar, a clamping spring, a housing and a lever, wherein the lever has a bearing plate with a partially circular outer contour for mounting the lever in a counter bearing, and wherein the lever has a follower which is designed to move the clamping arm out of a closed position into an open position when the lever is actuated.

A connecting bridge for the transmission of an electrical current between two electrically conducting components has at least two U-shaped cross-connectors each composed of electrically conductive sheet metal which are arranged nested in one another. An arrangement includes the connecting bridge and at least one busbar.

A conductor terminal with a busbar piece and a clamping spring. The clamping spring has a clamping limb which is oriented towards the busbar piece in order to form a clamping point for clamping an electric conductor between the clamping limb and the bus bar piece, a spring bracket which adjoins the clamping limb, and a contact limb, a vertical section of which extends transversely to the bus bar piece. The vertical section of the contact limb has a recess with edges which surround the bus bar piece. The bus bar piece has a contact wall which adjoins the wall surface of the contact limb vertical section extending transversely to the busbar piece. The wall surface lying on the vertical section side facing away from the clamping limb, and which is designed to support the vertical section of the contact limb on the contact wall.

The present invention relates to a switching device arrangement, comprising a plurality of switching devices, which are mounted in common on a mounting profiled rail, in particular a top hat rail, wherein the switching devices are connected to a bus system comprising at least one data bus and/or energy bus for transferring control signals and/or for supplying energy, wherein the bus system is integrated at least partially into the mounting profiled rail and the switching devices have bus connections for connecting to the bus system in the mounting profiled rail.
