Abstract
An electric switch has an arc extinguishing mechanism that includes a plurality of splitter plates located adjacent to the switch contacts. An electromagnet coil is connected between one of the contacts and a splitter plate to produce a magnetic field that drives an arc into the extinguishing mechanism. The unique electromagnet coil is formed by a lamination of a plurality of flat open loops of conductive material alternating with layers of insulation. The flat open loops are interconnected to form a helical coil.
