Synchronised movement of a bistable device, from a multitude of monostable levers

A bistable device comprising

• a fixed baseplate,
• a first lever and a second lever,
• a first tappet associated with the first lever, a second tappet associated with the second lever, the first and second tappets integral with said respective first and second levers and disposed between the associated lever and the baseplate substantially aligned in a first direction, wherein the first and second levers are configured to be displaced relative to the baseplate so as to displace the associated tappet substantially in translation in the first direction,
• a member able to take two positions,
• a first rocker associated with the first lever, a second rocker associated with the second lever, the first and second rockers disposed between the baseplate and the associated tappet, the rockers each comprising two V-shapes which face the associated tappet, wherein a touch of the associated tappet in a first V-shape turns the associated rocker in a rocker direction and a touch of the associated tappet in a second V-shape turns the associated rocker in a direction opposite to the rocker direction,
• wherein each rocker is synchronised in a rotation and each rocker is synchronised with the member.
