Abstract (en)
[origin: US6191377B1] An electromagnetic switching device, in particular a high capacity contactor, includes switch contacts which are arranged inside interrupter chambers formed by an interrupter chamber housing. Also provided is a deionizing device which is in the form of an arcing chamber and assigned to each interrupter chamber with a switch contact. The arcing chamber is formed by arcing plates which are assembled to form a packet. In addition, a cover is provided for closing the interrupter chambers on the upper side. The uppermost arcing plate which faces the cover is configured as a shielding plate of each arcing chamber and has at least one upward bent clip. Recesses which correspond with the clips of the arcing chambers are formed on the underside of the cover. The arcing chambers can be fastened to the cover to provide an interlocking connection by plugging the clips into the recesses.
