Abstract (en)

[origin: US4614928A] An automatic switch wherein a movable switch lever bears a contact element which cooperates with a fixed contact element bonded to a ferromagnetic contact strip which serves to provide a compact arc-extinguishing device. The ferromagnetic metal strip is mounted on the side of the contact element and/or on the movable switch lever's contact element on the side(s) directed away from the electrical contact surface(s). The application of the metal strip, or "blow plate," substantially improves the process of conducting away contact arcs from the contact elements to a set of deionization plates mounted inside the switch assembly.
