Abstract
The invention is directed to an actuator mechanism operating with the energy of a spring which snap actuates an electrical switching apparatus such as a vacuum switching apparatus. The actuator mechanism includes parts which are arranged movably independently of each other, namely, for the cocking motion of the spring and for the switching motion transmitted to the switching contacts of the switching apparatus. These parts cooperate in such a manner that the force of the spring, after being cocked, acts on the part associated with the switching motion automatically. The actuator mechanism is suited, for instance, as a manually operable, fast-acting drive for vacuum power circuit breakers.
