Abstract

Das Relais besitzt einen Spulenkörper (1), der vorzugsweise aus Keramik besteht, mit einer Wicklung (2) und einem U-förmigen Kernjoch (5), dessen Enden von einem flachen Anker (9) überbrückt werden. Der Anker betätigt eine isolierende Schaltfeder (14) aus Keramik oder einem ähnlichen Material, welche an ihrem beweglichen Ende mit einem Brückenkontakt (14a) zwei Gegenkontakte überbrückt. Das Relais kann auch bei sehr kleiner Ausführung in hoher Umgebungstemperatur eingesetzt werden.

Figure 00000001
The relay has a coil former (1), which is preferably made of ceramic, with a winding (2) and a U-shaped core yoke (5), the ends of which are bridged by a flat armature (9). The armature actuates an insulating switching spring (14) made of ceramic or a similar material, which bridges two mating contacts at its movable end with a bridge contact (14a). The relay can also be used in a very small version in a high ambient temperature.
