The assembly has a mobile contact (1) mounted to rotate in a contact carrier between stable positions. A traction spring (4) with single or double strands is fixed to the mobile contact and the contact carrier according to an orientation perpendicular to a rotation axis of the mobile contact in the contact carrier such that the spring exerts distinct torques in stability positions limiting an angular variation of the mobile contact in the contact carrier. The stability positions result from a change of positioning of the spring with respect to the axis or the mobile contact. |
