Abstract

Bei einem Relais (2) mit einer durch ein Relaisgehäuse (3) hindurchgeführten Doppelleitung (4), deren eine, erste Leitung (6) mindestens ein bewegliches Kontaktelement aufweist, welches den Stromkreis der ersten Leitung (6) in einer ersten Relaisposition schließt und in einer zweiten Relaisposition unterbricht, und deren andere, zweite Leitung (7) durchgehend ausgebildet ist,
ist erfindungsgemäß vorgesehen, dass das Kontaktelement als Kontaktfeder (10) ausgebildet ist und dass die zweite Leitung (7) im Wesentlichen parallel zur Kontaktfeder (10) und vor deren Federfläche (16) verläuft.

Figure imgaf001
In a relay (2) having a through a relay housing (3) passed through a double line (4) whose one, first line (6) has at least one movable contact element which closes the circuit of the first line (6) in a first relay position and in a second relay position interrupts, and the other, second line (7) is formed continuously,
is inventively provided that the contact element is designed as a contact spring (10) and that the second line (7) substantially parallel to the contact spring (10) and in front of the spring surface (16).
