Abstract

L'invention concerne un interrupteur à poussoir comprenant : un substrat présentant une première surface sur laquelle sont disposés un premier contact fixe et un second contact fixe, le second contact fixe étant disposé autour du premier contact fixe, le substrat présentant également une deuxième surface située sur un côté opposé à la première surface, une troisième surface s'étendant de la deuxième surface à une section de coin dans la direction orthogonale à la première surface et une quatrième surface s'étendant parallèlement à la première surface à partir de la section de coin ; et un contact mobile électroconducteur disposé de sorte qu'une section périphérique de ce dernier est en contact avec le second contact fixe et, lorsqu'il est pressé, une section centrale de ce dernier vient en contact avec le premier contact fixe. Sur la quatrième surface, une paire de sections électroconductrices sont disposées à proximité des sections d'extrémité d'une paire de côtés de la troisième surface qui s'étendent dans une direction orthogonale à la première surface.
