Abstract
A vacuum interrupter latch release mechanism employs a pivotably mounted trigger action arm in cooperation with a support arm assembly to resist the force of a main spring until the normally closed interrupter must be opened. Rotating the trigger action arm causes a catch on the trigger arm to become disengaged from an associated stop provided on the support arm assembly and allows the support arm assembly to pivot under the force of the main spring while being resisted by its weaker support spring. The rotation of the support arm is accelerated by the main spring. After a short stroke, an associated linkage impacts a stop on the vacuum interrupter which then becomes opened. The large force of the main spring causes virtually no wearing effect on the catch and stop faces over long periods of continuous operation.
