Abstract
The switching point in a high or medium voltage switch contains two stationary switch pieces which are of cylindrical design and led coaxially into one another, to form an annular gap. A movable bridge switch piece constructed in the form of a contact ring fits into the annular gap when the switching point is closed. An electrodynamic drive comprising two coils moves the contact ring in the axial direction. By virtue of the low mass of the contact ring, the single moving part of the switching point can be switched on and off very quickly and efficiently.
