Abstract

Die Erfindung betrifft einen Niederspannungs-­ Lastschalter mit Sicherung, nachfolgend Sicherungsschalter genannt, dessen Sicherungseinsatz zwischen einem zusätz­ lich von einer Klappe abgedeckten Kopfkontakt und einem von einer Fußkontaktfeder angehobenen Fußkontakt eines Sicherungssockels angeordnet ist, in dessen Stromzufüh­ rung ein Lastschalter mit Fußkontakt und an einem Träger gehaltenen, von einer Kontaktfeder beaufschlagten Schalt­ kontaktstücken angeordnet ist, der ohne Sicherungseinsatz in geöffneter Stellung verriegelt ist (nach Patentanmeldung VPA 79 P 4004, DE-Aktenzeichen P 29 15 170.0-32). Nach der Erfindung ist vorgesehen, daß am Träger (80) für die Schaltkontaktstücke (81) ein Schieber (82) angeordnet ist, der bei hochgehobenem Fußkontakt (4) mittels einer Nase (83) an diesem ansteht und bei niedergehaltenem Fußkontakt (4) vorbeigreift. The invention relates to a low voltage Load switch with fuse, subsequently fuse switch called, the fuse link between an additional Lich head contact covered by a flap and one foot contact raised by a foot contact spring Fuse base is arranged in the power supply a load switch with foot contact and on a support held, acted upon by a contact spring switching Contact pieces is arranged, the fuse link is locked in the open position (after patent application VPA 79 P 4004, DE file number P 29 15 170.0-32). After The invention provides that the carrier (80) for the Switching contact pieces (81) a slide (82) is arranged, the with raised foot contact (4) by means of a nose (83) in contact with this and when foot contact is held down (4) reaches past.
