FRICTIONLESS SWITCHING DEVICE FOR OPENING AND CLOSING AN ELECTRICAL LINE, WITH IMPROVED OPERATING ACCURACY

摘要

A switching device for opening and closing an electrical line, including:
two fixed contact terminals separated from one another,an operating member, comprising a contact piece,at least one flexible strip comprising at least one end part attached to a fixed support, the flexible strip or strips being adapted to exert a return force on the contact piece to return it from its closed position to its open position in the absence of a motive force on the operating member,the operating member comprising two electrically insulating pusher arms, spaced apart from one another and each attached to an end part of the contact piece;each flexible strip comprising two other end parts, each attached to one of the two push arms or to a part of the operating member that is itself attached to, or forms an integral part of, one of the pusher arms.

1. Switching device for opening and closing an electrical line, comprising:
two fixed contact terminals separated from one another, an operating member, comprising a contact piece adapted to be moved axially between a closed position in which the contact piece is applied simultaneously to the two contact terminals, connecting them electrically, and an open position in which the contact piece is separated from the two contact terminals, at least one flexible strip comprising at least one end part attached to a fixed support, the flexible strip or strips being adapted to exert a return force on the contact piece to return it from its closed position to its open position in the absence of a motive force on the operating member, wherein the operating member comprises two electrically insulating pusher arms, spaced apart from one another and each attached to an end part of the contact piece, and wherein each flexible strip comprises two other end parts, each attached to one of the two push arms or to a part of the operating member that is itself attached to, or forms an integral part of, one of the pusher arms.
