Abstract
In a known drive arrangement in which the switching-off process is initiated after actuation, for example, of an electromagnet by a pin secured to an "off"-trigger shaft as a result of rotation of the latter, thereby enabling a roller of the switching lever to run past the "off"-trigger shaft, the switching-off process occurs when the switching lever has rotated back and the articulated lever systems have moved out of the extended position. However, as the switching lever moves past, it strikes the "off"-trigger shaft. In order to reduce the resultant wear of the "off"-trigger shaft (6) and to actuate the wiping contact (11') associated with the "off"-trigger shaft (6) only during the switching-off process, so as to attain an even greater number of switching cycles, the switching lever (1) has a circular segment (7) with the peripheral surface (9) of which the "off"-trigger shaft (6) is operationally connected in any position of the switching lever (1). Detachably mounted on the "off"-trigger shaft (6) is a trigger bar (11) for connecting and disconnecting a wiping contact (11'). The drive arrangement can also be used for small oil-volume power circuit breakers.
