Abstract (en)
[origin: WO2007113089A1] With regard to an insulating switching rod for initiating a drive movement into a moving contact of an electrical contact system of a switching device, and for producing a contact force when the contact system is in the closed state, with a clamping apparatus which is arranged in a cavity for a drive element of the switching rod in order to maintain the contact force, which has a greater contact force with a compact design, and ensures constant spring characteristics as well as low wear over the entire useful life, it is proposed that the clamping apparatus comprises a helical compression spring arrangement.
