Abstract (en)
Method and device to free contacts in timers employing rotary disks that bear the required programme substantially on their circumferential periphery, a movable contact (20) having one end operating continuously on a common contact (24) and having its other end cooperating with a first transit contact (25) or with a second transit contact (26), the movable contact (20) being actuated by the periphery of the rotary timer disks (23) which acts on a feeler element (35) of a lever (21) able to rotate about a rotation pivot (22), a spring (27) being located between the movable contact (20) and the lever (21) and imparting to the movable contact (20) a lateral traversing movement (29) and a lengthwise traversing movement (30), in which method when the spring (27) cannot actuate the movable contact (20) owing to adherence of the latter (20) to the first transit contact (25), a second abutment (41) included on the movable contact (20) acts on the lever (21), which comprises a second inclined surface (39) having an angle of inclination " beta ", the second inclined surface (39) inducing in the movable contact (20) a lengthwise traversing movement (30), which also displaces the movable contact (20) sideways and thus breaks the adherence of the same (20) and restores the resilient action of the spring (27).
