Abstract

Das elektrische Schaltgerät ist versehen mit einer mit abbrandfesten Kontakten ausgerüsteten Kontaktanordnung, welche mindestens einen entlang einer Achse (3) beweglichen Kontakt (1) und mindestens einen zylindrisch ausgebildeten, für die Aufnahme des beweglichen Kontakts (1) vorgesehenen Gegenkontakt (4) aufweist.The electrical switching device is provided with a erosion-proof contacts equipped contact arrangement, which at least one movable along an axis (3) Contact (1) and at least one cylindrical, provided for receiving the movable contact (1) Has counter contact (4).

Es soll ein elektrisches Schaltgerät angegeben werden, welches mit einfachen Mitteln für das Einschalten vergleichsweise grosser Ströme ertüchtigt ist. Dies wird dadurch erreicht, dass in der Kontaktanordnung mindestens ein Isolierrohr (12) vorgesehen ist, welches einen abbrandfest ausgerüsteten Kontaktbereich radial begrenzt.

Figure 00000001
An electrical switching device is to be specified which is capable of being switched on with simple means for switching on comparatively large currents. This is achieved by the fact that at least one insulating tube (12) is provided in the contact arrangement, which radially delimits a contact area that is resistant to erosion.
