<p>A snap-fast switch, comprising a push-button 2 adapted to rotate about a fulcrum "—‹", a housing structure 3, at least one rod 4 constrained to one end of the push-button 2 and countered by an elastic means 41. The switch comprises an actuating mechanism comprising a first oscillating snap means 61, alternatively acting upon one contact (5A, 5B) of at least one module "M", and a second oscillating snap means 62, which is acted upon by said rod 4. Said second snap means 62 acts upon the first snap means 61 and causes it to switch, so that means 61 acts upon the opposite contact (5A or 5B). The switch comprises an interlock means adapted to lock the first snap means 61 at the end-of-travel points, and a release element adapted to disengage first snap means 61 when push-button 2 reaches a predetermined angle of inclination "±".</p> |
