Abstract

Die Erfindung betrifft eine Anordnung zur Schaltstellungs- und Abbrandanzeige mindestens eines feststehenden und mindestens eines beweglichen Kontaktes eines elektrischen Schaltgerätes. Es sind zwei einander zugeordnete Anzeigeelemente (7,8) vorgesehen, von denen das eine Anzeigeelement (7) ortsfest bezüglich des feststehenden Kontaktes (401) verbunden ist und das andere Anzeigeelement (8) fest bezüglich des beweglichen Kontaktes verbunden ist. Das zweite Anzeigeelement (8) macht die Schaltbewegung des beweglichen Kontaktes (411) mit. Aus der jeweiligen Stellung der Anzeigeelemente (7,8) zueinander ist die Schaltstellung und in der Schaltstellung Ein gleichzeitig der Abbrand der Kontakte (401, 411) ablesbar.

The invention relates to an arrangement for switching position and erosion display of at least one fixed and at least one movable contact of an electrical switching device. Two mutually associated display elements (7, 8) are provided, of which one display element (7) is connected in a fixed position with respect to the fixed contact (401) and the other display element (8) is connected in a fixed manner with respect to the movable contact. The second display element (8) makes the switching movement of the movable contact (411). The switch position and, in the switch position On, the erosion of the contacts (401, 411) can be read from the respective position of the display elements (7, 8).
