  • Patent number: 7868261
    Abstract: The present invention relates to a switch comprising a casing (1, 9), an actuator member (2, 3) pivotably mounted in the casing (1, 9) and integral with a switching control rod (10), capable of occupying a central position (A) and a rocked position (C), a pusher (5) slidably mounted in the actuator member (2, 3) in an incoming/outgoing direction substantially parallel to the plane of symmetry of the rocking, remarkable in that it further comprises a rockably mobile lock (4) on an elastic support (11), said lock (4) being distinct from the pusher (5) and capable of assuming a first position where it is interposed on the trajectory of the actuator member (2, 3) and a second position where it cooperates with the pusher (5) so that a thrust on the pusher (5) urges the lock (4) and allows the latter to disengage from the trajectory of the actuator member (2, 3) towards the rocked position (C).

  • Patent number: 4743464
    Abstract: According to the process, there is applied to one face of a relatively rigid isolating support (1) a first matrix arrangement of areas (3) connected by conductor tracks of lines (4). Said arrangement is coated with a thin layer of isolating lacquer (5) and a second matrix arrangement of areas (6) is set in place on the lacquer layer with their conductor tracks of columns (7) to obtain, by bringing together an armature towards each stud comprised of two areas (3, 6), a capacitive connection.
