FIELD: electrical engineering.SUBSTANCE: disclosed is an arc extinguishing plate for an electric switch, containing the first installation section and the second installation section for installing an extinguishing plate into appropriate recesses of the switch with formation of an asymmetrical arc propagation channel between the side sections of the plate. First installation section (468) and the second installation section (470) have different shapes as compared to each other.EFFECT: technical result: possibility to install arc extinguishing plates in an electric switch, so that an arc propagation channel formed by a plurality of arc extinguishing plates can be reinforced by appropriate recesses in the switch to receive arc extinguishing plates, and the assembly of such a switch is simplified.15 cl, 4 dwg |
