Profiled arc splitter plate

An arc splitter plate for a switch having a fixed contact and a movable contact, said arc splitter plate comprising:

• a body having a length being a distance between a first set of two parallel planes defined at a proximal end and a distal end respectively with reference to the movable contact, and a width being a distance between a second set of two parallel planes, each plane of said second set being perpendicular to the planes of said first set, said body defining an operatively inverted substantially V-shaped recess having a center notch with diameter D in a range of 2-4 mm, provided at a vertex of said recess, said vertex located at a first distance from the plane of said first set defined at said proximal end and a second distance from the plane of said first set defined at said distal end, said first distance being in a range of 75-80% of said length, said second distance being in a range of 20-25% of said length;
• and
• a first protrusion and a second protrusion defined on either side of said center notch along an inclined side walls of said V-shaped recess, at a third and fourth distance respectively from the plane of said first set defined at said proximal end, said third distance being in a range of 25-30% of said length, said fourth distance being in a range of 60-65% of said length,
• the movable contact of the switch displaceable through said recess without contacting the inclined side walls, in a spaced apart manner from said protrusions and said center notch, a clearance between the inclined side walls and a tip of the movable contact being in a range of 3-4 mm and a maximum distance between the inclined side walls being in a range of 75-80% of the width.
