Abstract
Exemplary embodiments relate to a drive for a switch disconnector having C or O switching capacity and a switching pin acting as switching contact. A spindle drive is driven by an electric motor and has a spindle nut. An actuating element, which is loaded by a compression spring and is capable of pivoting about a fixed pivot point, is acted upon by the spindle nut. The actuating element for its part interacts with an actuating apparatus which actuates the switching pin.
