Abstract

Bei einem elektromechanischen Relais zur Betätigung wenigstens eines Arbeitsstromkreises besteht das Betätigungselement aus einem Werkstoff mit Formgedächt­ niseigenschaft und wird durch ein Rückstellelement im stromlosen Zustand in eine gegenüber seiner Ursprungs­ form verzerrten Form gehalten. Bei Anliegen eines Schaltstromes am Betätigungselement, das vorzugsweise als stromdurchflossene Spirale ausgebildet ist, kehrt dieses gegen die Kraft des Rückstellelementes in seine Ursprungsform zurück und betätigt über ein Stellglied in einem Arbeitsstromkreis angeordnete Kontaktpaare.
