Abstract

An insulating switching rod has a drive element for initiating a drive movement in an electrical contact system of a switching device and for producing a contact force when the contact system is in the closed state. The system further includes a clamping apparatus for the drive element of the switching rod in order to maintain the contact force. The object is to produce a greater contact force with a compact design and ensure constant spring characteristics as well as low wear over the entire useful life. For that purpose, the switching rod and the drive element can be directly or indirectly connected to one another by way of a plug and latching connection.
