    摘要： Linear control apparatus for a circuit-breaker, the apparatus including a slidably-mounted tubular arm actuated by a solenoid, and a "disengagement" first slide which presses against the tubular arm, the first slide being subjected to a first spring assembly. The control end of the drive rod is coupled to the tubular arm via at least one projecting portion passing through a respective longitudinal slot provided along the tubular arm. The control apparatus includes an "engagement" second slide to which the drive rod is fixed via its projecting portion, the engagement second slide being subjected to an "engagement" second spring assembly which displaces it from the circuit-breaker disengaged position to the circuit-breaker engaged position under the action of second control means.

    摘要： A transmission assembly is for an electrical switching apparatus. The electrical switching apparatus includes a housing, a mount, at least one charging mechanism, and a pair of separable contacts. The transmission assembly has a drive assembly and a transfer assembly. The drive assembly includes a rotary driving member, a stored energy mechanism, and a linear driving member partially extending into the stored energy mechanism and being coupled to the rotary driving member. The transfer assembly cooperates with the drive assembly and the separable contacts and includes a sliding transfer component. The transmission assembly moves between a LOADED OPEN position, an UNLOADED CLOSED position, a LOADED CLOSED position, and an UNLOADED OPEN position. When the transmission assembly moves from the LOADED OPEN position to the UNLOADED CLOSED position, the linear driving member drives the sliding transfer component in a generally linear direction, thereby closing the separable contacts.
