Abstract
An electromechanical switch of the contactor or circuit-breaker type with adjacent contacts, which are provided on respective mobile and fixed contact parts. This arrangement defines a narrow ionization slot which is maintained at the start of contact opening in order to cause a secondary arc to fire substantially perpendicular to the contact opening direction constituting a shunting arc to eliminate the time duration of the contacts and switch legs.
