Gegenstand der Erfindung ist die Verwendung von Phosphorbronze-Blei-Legierungen zur Herstellung elektrischer Kontakte. Solche Legierungen sind an sich bekannt. Neu ist nur ihre angegebene Verwendung. Sie zeichnen sich durch große Festigkeit und Elastizität aus und haben nur geringe Neigung zum Funkenbilden beim öffnen der Kontakte. Besonders eignen sie sich deshalb zur Her-Stellung von Schleifkontakten.The invention relates to the use of phosphor bronze-lead alloys for making electrical contacts. Such alloys are known per se. New is only their specified use. They are characterized by great strength and elasticity and have only a slight tendency to form sparks when the contacts open. They are therefore particularly suitable for making sliding contacts.

Als besonders vorteilhaft hat sich eine Legierung folgender Zusammensetzung herausgestellt: 4 bis S1U °/o Zinn' ! bis 4 % Blei> 0,5 bis 0,25 % Phosphor und als Rest Kupfer.An alloy of the following composition has proven to be particularly advantageous: 4 to S 1 U ° / o tin ! up to 4% lead > 0.5 to 0.25% phosphorus and the remainder copper.

Hieraus angefertigte Schleiffedern zeigten, wie angestellte Versuche ergaben, nach 5 Millionen Kontaktschließungen erst eine geringe Abnutzung, während gewöhnliche Bronzeschleiffedern bereits nach 3 Millionen Kontaktbeanspruchungen verbraucht sind.Slider springs made from this showed, as made tests have shown, after 5 million Contact closures show only slight wear, while ordinary bronze slide springs are already used up after 3 million contact loads.
