An electrical switching arrangement comprising an electrical conductive plate (P) resting on a spring (M) which in turn is supported by a stationary base (B), said plate bearing at least one movable contact (C3 or C4), and at least one lower stationary contact (C1 or C2) apt to engage at least said movable contact (C3 or C4), and at least one push button for applying an operating force (F) to said plate (P), one of which movable contacts (C3 or C4), as a result of the lowering of the push button for applying force (F), engaging one of said stationary contacts (C1 or C2), which operating push button presses said plate, bearing at least one movable contact (C3 or C4) at a position between a point of substantial alignment with said movable contact (C3 or C4) and any point whatsoever between said movable contact and the spring (M). A switch carried out in accordance with said switching arrangement.
Ce dispositif de commutation électrique comporte une plaque conductrice (P) reposant sur un ressort (M) lui-même soutenu par une assise immobile (B), cette plaque portant au moins un contact mobile (C3 ou C4), et au moins un contact inférieur immobile (C1 ou C2) capable de venir au contact du contact mobile (C3 ou C4). Ce dispositif comporte également un bouton poussoir servant à exercer une force (F) sur la plaque (P). De la sorte, l'un des contacts mobiles (C3 ou C4), du fait de l'abaissement du bouton poussoir, vient au contact des contacts immobiles (C1 ou C2). Lorsqu'il est sollicité, le bouton poussoir appuie sur la plaque porteuse d'au moins un contact mobile (C3 ou C4) et la positionne entre un point de quasi-alignement avec le contact mobile (C3 ou C4) et tout point, quel qu'il soit, se trouvant entre le contact mobile et le ressort (M). L'invention concerne également un commutateur équipé de ce dispositif de commutation.
