Abstract:
1. A double-action tactile-effect electrical switch comprising: an insulative support, an upper face of which that lies in a horizontal plane and carries at least three fixed electrical contacts comprising: a triggering member, which is elastically deformable from a stable rest state by the action of an actuating member acting in a vertical direction, the triggering member comprising a lower peripheral annular area adapted to come simultaneously into bearing engagement with the two first peripheral contacts to make a first switchpath, and a domed upper central section on which the actuating member acts, wherein the domed upper central section is deformable in order to make an electrical connection between the two fixed first contacts and the central third electrical contact, to make a second switchpath consecutively to the making the first switchpath; wherein, in its stable rest state, the triggering member occupies either: wherein the switch includes a spring disposed vertically between the support and the triggering member and which is compressible vertically to enable the triggering member to move from its initial high position to its final low position, and wherein, in the initial high position of the triggering member, the lower peripheral edge that delimits the annular area lies in a plane that forms an acute angle with the horizontal plane, and, in the low final position, the lower peripheral edge lies in a plane parallel to the horizontal plane and bears on the two first peripheral fixed contacts.
