A driving arrangement for electrical switches is described, which has a mechanical independent trip release mechanism. Toward this end, a coupling lever 46 is situated between a driving lever 26 and a coupling bar 27, whereby said coupling lever 46 is arranged on the coupling bar 27 and operated by a stationary configuration. For that purpose, an independent trip release lever 56 has been provided which is pivoted together with an activating element 55 for the coupling 46 by an off-switch jack 40 during the switch-off mode. The described independent trip release mechanism has been designed for manual or self-activating release as well as activation upon removal of a movable switch from a regulating cell. The new driving arrangement is especially suitable for applications with medium voltage type output switches, such as switches equipped with vacuum switching tubes.
