FIELD: electricity.
SUBSTANCE: invention deals with design of a spring-actuated circuit closing unit of the switching mechanism for a compressed-air circuit breaker containing a connecting spring, the first spring socket element, the second spring socket plate, the spring guide pin the both end pieces thereof are connected to the first spring socket element and the second spring socket plate and a supporting yoke; the guide pin is positioned so that to be encased by the connecting spring to provide for the connecting spring direction and support; the supporting yoke serves to support the second spring socket plate of the connecting spring so that to enable rotation within a restricted angle.
EFFECT: simplification of manufacture combined with enhanced cost-efficiency due to press moulding technology deployment.
