<p>The spring (90) includes a feeler element (94) interacting by sliding over a bearing surface 80a of the moving contact (22) so as to alter the point of application (103) of the pressure force P in the second active repulsion position, entailing a reduction in the return torque before action by the mechanism (58). The moving contact (22) is fork-shaped, being articulated on an eccentric spindle (84) parallel to the axis of rotation of the bar (70). The spiral spring (90) is mounted floating in the hollow (92) of the bar (70), and comprises two helical windings (90a), (90b) of metal wire. <IMAGE></p> |
