ARRANGEMENT FOR AN ELECTRICAL SWITCH ELEMENT WITH A SEAL CONFIGURATION

摘要

The invention concerns an arrangement for an electrical switch element (1), comprising an switch chamber (3) for receiving contacts (5) that can be closed and/or opened, at least one movable propulsion element (13) protruding through an opening (11) of the switch chamber (3) to open or close the contacts (5), and a seal configuration (15) surrounding the propulsion element (13), by which the opening (11) is sealed at least in an end position (E) of the propulsion element (13), the seal configuration (15) having an annular bulge (23) surrounding the opening (11) and an annular flange (25) on the propulsion element (13). In order to provide an arrangement for an electrical switch element (1) that is capable of eliminating any arcs quickly and effectively and to protect elements outside of the switch chamber (3) from the plasma formed by the arcs, whilst simultaneously providing an especially compact, inexpensively produced circuit element, the invention provides for the annular flange (25) to abut the annular bulge in the end position (E) of the propulsion element (13).
