Abstract
A multiposition microswitch that includes a cavity, a mobile portion made of a deformable material extending above the cavity, at least three conductive tracks extending on the cavity bottom, and a contact pad on the lower surface of the mobile part. The mobile part is capable of deforming, under the action of a stressing mechanism, from an idle position where the contact pad is distant from the conductive tracks to an on position from among several distinct on positions. The contact pad electrically connects, in each distinct on position, at least two of the at least three conductive tracks, at least one of the conductive tracks connected to the contact pad in each distinct on position being different from the conductive tracks connected to the contact pad in the other distinct on positions.
