Abstract

A switching-device tripping apparatus for a switching device includes contact pieces that can be moved relative to one another. Relative motion between the contact pieces is generated by a gear or transmission configuration. The gear or transmission configuration has a pawl in order to control motion of the contact pieces relative to each other. First and second tripping devices are provided, which work or operate the same pawl and drive the same pawl.
