ABSTRACT:
A switch capable of individually switching two circuits through a double action of an actuator. The switch comprises: an actuator adapted to slide in a casing by a given stroke; a spring for energizing the actuator toward an initial position; a locking mechanism for preventing the actuator from returning toward the energizing direction by the spring at an intermediate position in the stroke; primary-side contacts adapted to be switched by means of the actuator in the course of movement thereof from the initial position to the intermediate position in the stroke; and secondary-side contacts adapted to be switched by means of the actuator in the course of movement thereof where the actuator further reciprocates against the spring from the locked state at the intermediate position.
