A bistable MEMS microswitch produced on a substrate and capable of
electrically connecting ends of at least two conductive tracks, including
a beam suspended above the surface of the substrate. The beam is embedded
at its two ends and is subjected to compressive stress when it is in the
non-deformed position. The beam has an electrical contact configured to
produce a lateral connection with the ends of the two conductive tracks
when the beam is deformed in a horizontal direction with respect to the
surface of the substrate. Actuators enable the beam to be placed in a
first deformed position, corresponding to a first stable state, or in a
second deformed position, corresponding to a second stable state, and the
electrical contact ensures connection of the ends of the two conductive
tracks.
