Abstract

Um eine umgebungsunabhängige Kontaktgabe zu errei­ chen, sind zwei hermetisch verschlossene Kontaktpillen (31, 32) vorhanden. Jede Kontaktpille weist einen Umschaltekon­ takt auf und besitzt als bewegliches Glied eine Membran (1, 1′) aus elektrisch und magnetisch leitendem Material, welche Membran infolge des durch einen Permanentmagneten (35) bewirkten und durch den Kern (37) einer Steuerspule (36) flies­ senden Magnetflusses an entsprechenden Kontaktpolen (5, 6′ oder 6, 5,) haftet. Für die Umsteuerung des Relais genügt ein Stromimpuls durch die Steuerspule, welcher einen Steuerfluss bewirken muss, der nur wenig grösser ist als der Permanent­ magnetfluss, weil sich die beiden Flüsse nach eingeleiteter Um­ teuerung in ihren Wirkungen unterstützen. Dank dieser Unter­ stützung ist die benötigte Steuerleistung so gering, dass eine direkte Ansteuerung durch TTL-Schaltungen möglich ist. Durch andere Anordnung des Permanentmagneten im Ma­ gnetkreis sind auch monstabile Relais realisierbar. To achieve contact regardless of the environment chen, are two hermetically sealed contact pills (31, 32) available. Each contact pill has a switch con clocks and has a membrane as a movable member (1, 1 ′) made of electrically and magnetically conductive material, which Diaphragm due to the permanent magnet (35) caused and flows through the core (37) of a control coil (36) send magnetic flux to corresponding contact poles (5, 6 ′ or 6, 5,) is liable. One is sufficient for reversing the relay Current pulse through the control coil, which is a control flow must effect that is only slightly larger than the permanent magnetic flux, because the two rivers Support the effects of inflation. Thanks to this sub support, the required tax output is so low that a direct control by TTL circuits is possible. By arranging the permanent magnet differently in Ma monstable relays can also be implemented.
