<p>The mechanism of the invention is designed such that a spring (5) is anchored to a lever (2) and an arm (6), so as to provide storage of energy by expanding when the lever (2) is subjected to an actuation force (1), releasing said energy immediately before a contact (8), movably secured to a pole bridge (7), connects with a contact (9), thereby enabling, independently of the actuation force (1), the contacts to achieve good connection and a contact spring (14) to be compressed. Such motion is ensured by a journaled wheel (3) traveling over the rest surface of the pole bridge (7).</p> |
