Abstract
An operator is provided that includes a common drive for charging an operating mechanism and for driving a functional accessory device in predetermined coordinated relationship. The common drive in a specific embodiment is provided as a drive shaft at the output of a drive train. The operating mechanism is charged as the drive shaft is rotated from a first to a second predetermined position. The functional accessory device is also driven via the drive shaft; the functional accessory device being operated from a first predetermined operational state to a second predetermined operational state in response to the rotation of the drive shaft between the predetermined positions. When desired, the functional accessory device is operated from the second predetermined operational state to the first predetermined operational state by subsequent rotation of the drive shaft to the first predetermined position. The operating mechanism is controlled thereafter to close the contacts of one or more interrupting units. The operating mechanism is capable of immediately opening the contacts of the one or more interrupting units after closing. After opening of the contacts of the interrupting unit an…
