Abstract: The present invention provides an actuator member of the multifunction key type, in particular of the navigation key type, consisting of a rigid button mounted with limited mobility and a separate detector component having a plurality of active sites. The button has underside formations each intended to come into contact with one of the active sites. Three active sites are disposed at the corners of a triangle, wherein a non-active bearing site is disposed between two of the active sites, alone or in conjunction with the third active site, so as to allow tilting of the button by pivoting on the non-active site toward one of the first two active sites situated on respective sides thereof until the corresponding formation comes into contact with one of the active sites to activate it, for example by compressing it or depressing it.

Which member includes three active sites which are disposed at the corners of a triangle and wherein a non-active bearing site disposed between a first two of said active sites, alone or in conjunction with the third site, authorizes tilting of said button by pivoting on said non-active site toward one of said first two active sites situated on respective sides thereof until the corresponding formation comes into contact with one of said active sites to activate it, for example by compressing it or depressing it.
