Power-rail adapter and power rail
First Claim
1. In combination:
- a power rail comprisinga generally longitudinally extending profile having a pair of transversely confronting sides only one of which is formed with a longitudinally extending and inwardly open coding groove, the sides forming a longitudinally extending and open slot, anda pair of upper longitudinally extending and transversely spaced conductors on the profile sides; and
an adapter comprisinga body fittable to the rail,a switch shaft extending from the body along an axis and pivotal thereabout relative to the body between a removing position and an installed position, the shaft extending into the slot when the body is fitted to the rail,a pair of radially projecting contacts, anda radially projecting coding stud on the shaft, the shaft being rotatable in a first predetermined orientation of the body relative to the rail into the installed position with the coding stud engaging in the coding groove and the contacts engageable with the conductors, the other side of the profile being shaped so as to engage and prevent rotation of the shaft from the removing position into the installed position when the body is not in the first predetermined orientation relative to the rail.

Abstract
A power-rail adapter (39) for mechanical and electrical connection of a light fixture (10) and/or of an operating unit (15) of the light fixture with a power rail (28), comprising at least a switch shaft (41) that can be pivoted between a removing position in which the adapter is removable from the power rail and an installing position in which the adapter is fixed to the power rail is illustrated and described.
A specific feature is amongst others that a coding stud (66) is provided on the switch shaft and that a coding groove (77) is provided at the power rail in which the coding stud can be introduced only with a single relative orientation of the adapter (39) with respect to the power rail (28) with pivoting of the switch shaft from the removing position into the installing position.
