Bistable switch intended to be fitted in an aircraft

A bistable switch for an aircraft, the bistable switch comprising:

• a frame and a control means which is intended to be operated by a user, the control means being movable relative to the frame between a first control position and a second control position,
• characterised in the bistable switch further comprises a leaf spring which is mechanically connected to the frame and to the control means, the leaf spring being arranged in a buckling state and being configured to adopt a first stable buckling position when the control means is in the first control position and to adopt a second stable buckling position when the control means is in the second control position and to switch in each of the two first and second buckling positions,
• the control means comprising a first part capable of pivoting relative to the frame around a direction perpendicular to the direction of flexion of the leaf spring,
• the switch comprising a second part movable in translation relative to the frame and interposed between the first part and the leaf spring, the second part including a rectilinear groove, the second part being fixed to the frame by means of a sliding connection allowing movement of the second part in a direction perpendicular to the rectilinear groove,
• the first part and the second part being configured to transform a rotational movement of the first part relative to the frame into a translational movement of the second part relative to the frame, the first buckling position and the second buckling position are arranged symmetrically relative to the axis of rotation of the control means.
