    • Die Erfindung betrifft ein Schaltelement für Befehlsgräte für den Frontplatteneinbau mit in einem Gehäuse angeord­neten Kontakten und einer über einen ferdervorgespannten, geführten Stößel (40) betätigbaren, unter Federkraft ste­henden Kontaktbrücke (45). Um sowohl kleinste als auch höhere Ströme bei verschiedensten Spannungen schalten zu können, ist vorgesehen, daß die Kontaktbrücke (45) und die Kontaktbleche (35) endseitig jeweils ein aufgeschweißtes Mikroprofil (46, 46a) besitzen, das einen zum jeweiligen Kontakt gerichteten Spitzenbereich (50) mit einer Auflage aus Gold oder einer Goldlegierung aufweist, die über einer Edelmetall-Legierung (49) angeordnet ist, welche auf ein Trägermaterial aufgeschweißt ist.

    • A switch is disclosed in which manual adjustment of a contact spring pileup is avoided by closely controlling the interaction between (1) the contact springs, (2) a movable actuator including a plurality of cam surfaces, each of which is associated with an individual contact spring, and (3) a frame for supporting the actuator. This is achieved by molding a cam follower to one end portion and a mounting element to the other end portion of each contact spring. The mounting elements of the contact springs are positioned in engagement with one another and are secured to the frame. The mounting elements serve to orient the contact springs at a particular angle with respect to one another and accurately locate the contact springs and thereby the cam followers with respect to the cam surfaces of the actuator. The cam followers in combination with the associated cam surfaces serve to locate and provide a predetermined bias to the contact springs.

    • A DC contactor providing increased magnetic efficiency, reduced contact bounce, and shorter arc time has a movable contact carrier bar pivotally mounted relative to a clapper armature so as to prevent tilting about its longitudinal axis and eliminate rotational bounce; a pre-loaded contact pressure spring which resiliently urges the contact carrier bar against the armature; an armature retainer spring which resiliently urges the pivoted end of the armature backward and downward against the yoke so as to displace dirt accumulated in the pivot area and prevent jamming of the armature; a generally hyperbolic magnetic pull characteristic with the knee at approximately the one-half armature travel position and the magnetic pull at the two-thirds armature travel position being approximately twice the magnetic pull at the knee to thus provide relatively high magnetic pull per ampere in the region above the knee; the magnet gap between armature and core at the point of contact engagement being less than that at the knee of the characteristic so that the force of the pre-loaded contact pressure spring tending to reduce contact bounce can be greater than the magnetic pull at the knee and also several times greater than the force of the return spring at the contact touch point, and the total return spring and contact pressure spring forces can be increased to overcome residual mmf and accelerate the contacts to open position at a higher separation rate.
