Abstract
The light arc extinguishing chamber has two plates (10) of ferro-magnetic material positioned transversally to the direction of the light arc. The plates are U-shaped, with forwardly drawn arms (11,12) on both sides of the contacts. They are held together by side pieces (20) of light arc-resistant insulating material. The side pieces are positioned on the inside of the extinguishing plate arms. An inwardly facing tongue in the top of each arm is fixed in a hole in the side pieces to hold together the plates as a composite unit. The tongues are also riveted on the inside of the side pieces. One side edge of each side plate has a recess for fixing the plates at a distance from one another. (Provisional basic advised week 90/04).
