Abstract

At the start of the closing movement, a plunger (1) is forced back against the influence of a spring (2) until its end edge (4) slides away over the crest of a sphere (5), as a result of which the restraint is ended. This makes it impossible for the circuit to be connected to a load just by the operating device of the switching apparatus being tilted for only a short time duration. <IMAGE>
