A bistable device including a fixed baseplate, at least two levers, a tappet rigidly secured to between each lever and the baseplate and aligned in a first direction, where a lever is capable of displacement relative to the baseplate so as to displace the associated tappet substantially in translation in the first direction, and a member that is able to take two positions, the device additionally including a rocker associated with each lever, arranged between the baseplate and the associated tappet, including two V-shapes facing the associated tappet, where the associated tappet in the first V-shape tends to turn the associated rocker in a first direction and the associated tappet in the second V-shape tends to turn the associated rocker in a second direction opposite to the first direction, the rockers being synchronized in rotation and the rockers being synchronized with the member.

A switch mechanism has a conductive mobile contact carrier with two lateral branches pivotally engaged with a central hub. The lateral branches of the conductive mobile contact carrier are continuous with its middle branch, each being joined to the latter by a large radius elbow, and the conductive mobile contact carrier bears on the output contacts through its lateral branches. The output contacts are near the central hub so that the lateral branches of the conductive mobile contact carrier are subjected to a local transverse self-cleaning movement when it comes into contact with the output contact. Applications include single-throw and double-throw switches.
