Abstract

Dieses Schaltgerät weist eine mit abbrandbeständigen Kontakten ausgerüsteten Kontaktanordnung auf, welche mindestens einen entlang einer zentralen Achse (2) beweglichen Kontakt und mindestens einen für die Aufnahme des beweglichen Kontakts vorgesehenen Gegenkontakt umfasst. Einer der beiden Kontakte weist einen Fingerkorb (25) auf, der mit einzelnen, voneinander durch in Richtung der zentralen Achse (2) erstreckte radiale Schlitze (26) beabstandeten, federnden Kontaktfingern (13) versehen ist. Es sind Mittel vorgesehen, welche verhindern, dass sich bei einem Zusammenziehen der Kontaktfinger (13) in Richtung der zentralen Achse (2) die seitlichen Flanken (29) der Kontaktfinger (13) im Bereich der Kontaktflächen (27) im vorderen Teil der Kontaktfinger (13) berühren können, sodass kein Verschweissen der Flanken (29) der Kontaktfinger (13) auftreten kann.

Figure 00000001
This switching device has a contact arrangement equipped with erosion-resistant contacts, which comprises at least one contact movable along a central axis (2) and at least one mating contact provided for receiving the movable contact. One of the two contacts has a finger basket (25) which is provided with individual resilient contact fingers (13) spaced apart from one another by radial slots (26) extending in the direction of the central axis (2). Means are provided which prevent the side flanks (29) of the contact fingers (13) in the region of the contact surfaces (27) in the front part of the contact fingers (13) from contracting when the contact fingers (13) are pulled in the direction of the central axis (2). 13) can touch, so that no welding of the flanks (29) of the contact fingers (13) can occur.
