Abstract
PURPOSE: To operate an electric contact point from low load to high load under relatively low contact pressure accurately in long useful life by constituting an electric contact from an Au-Pd alloy contact point layer adhered to a contact point matrix material through Cu, Ni and Au strike plating layer.
CONSTITUTION: An undercoating 9 constituted from two layers of a Cu layer 7 and an Ni layer 6 to a surface of a contact point matrix material 8 such as Fe or the like and, onto this undercoating 9, is formed an Au strike plating layer 5 with thickness of 0.1μm and, moreover, an Au-Pd alloy contact point layer 1 comprising columnar structure 3 containing Pd: 10W50% is formed thereon in the thickness of 1W15μm by a sputtering method. Because a contact point layer 1 is a columnar structure 3, even if the said layer is consumed by spark or the like, a new contact point surface 2 similar to an initial surface is developed always and an excellent contact point property is maintained at all times.
