Abstract

Das Relais besitzt ein Magnetsystem mit einem Anker (44), welcher über ein Betätigungsglied (3) auf eine Schaltfeder (21) wirkt. Diese Schaltfeder besitzt in einer Ebene ineinanderliegend und gegenseitig entkoppelt eine rahmenförmige Kontaktfeder (22) sowie eine gabelförmige Rückstellfeder (23), wobei letztere über mindestens zwei in einer Linie parallel zur Schwenkachse liegende Anlenkpunkte (23b,33) das Betätigungsglied (3) führt. Dadurch ergibt sich ein kompakter Aufbau mit wenig Einzelteilen und mit einer sehr reibungsarmen Betätigung.

Figure 00000001
The relay has a magnet system with an armature (44), which acts on a switching spring (21) via an actuator (3). This switching spring has a frame-shaped contact spring (22) and a fork-shaped return spring (23) lying one inside the other and decoupled from one another, the latter guiding the actuating member (3) over at least two articulation points (23b, 33) lying in a line parallel to the pivot axis. This results in a compact structure with few individual parts and with a very low-friction actuation.
