Publication number: 20140120743Abstract: A wire is provided for producing a sliding contact, wherein at least an inner core of the wire consists of a copper-silver alloy. A sliding contact is also provided having at least one such wire, wherein a counter-contact is provided whose conductive surface has at least one of the wires touch against it. The spring force of the wire acting on the conductive surface of the counter-contact effects electrical contacting between the wire and the counter-contact and the counter-contact is mobile with respect to the wire, such that the surface of the wire slides over the counter-contact when the counter-contact moves. Components having the sliding contact are also provided, including a potentiometric sensor, potentiometer, sliding dolly regulator, position sensor, rotary switch, electrical motor, generator, wind turbine, slip ring system, actuator, or current collector.Type: ApplicationFiled: June 12, 2012Publication date: May 1, 2014Applicant: HERAEUS MATERIALS TECHNOLOGY GMBH & CO.
