Abstract: A switch mechanism has a conductive mobile contact carrier with two lateral branches pivotally engaged with a central hub. The lateral branches of the conductive mobile contact carrier are continuous with its middle branch, each being joined to the latter by a large radius elbow, and the conductive mobile contact carrier bears on the output contacts through its lateral branches. The output contacts are near the central hub so that the lateral branches of the conductive mobile contact carrier are subjected to a local transverse self-cleaning movement when it comes into contact with the output contact. Applications include single-throw and double-throw switches.
Abstract: A marker device includes a plate receiving an identifying message and at least one pair of arms facing each other and adapted to attach the device to a support. Each arm includes in the gap between them a finger extending towards the plate. Over at least the width of the finger in the direction parallel to the lengthwise direction of the plate, the arms each lie alongside a respective opening in the plate providing access to the finger. One application of the device is to marking electrical conductors and/or electrical devices such as terminal blocks, for example, provided with an appropriate support.
Abstract: Trunking, in particular trunking for electrical apparatus, includes a body with inwardly directed lips and a cover adapted to be snap-fastened to the lips. The trunking further includes a cover jointing member extending transversely between the lips of the body to cover the end of the cover. At one end at least it is provided with a latch for locking it to the respective lip of the body.
Abstract: A device for butt-joining two sections of perforated cable tray includes a fishplate having on each side of a central area a latch member adapted to slide in a longitudinal slot with hoops adapted to cooperate with a line of perforations and to be locked therein by means of a comb member.
