に用いられている。In general, materials in which A9 or Ag alloy is coated on a metal base material have traditionally been used for various purposes because, in addition to the characteristics of the base material, they have excellent corrosion resistance, solderability, electrical connectivity, etc. unique to Ag.

It is known as an economical, high-performance conductor with excellent corrosion resistance, solderability, and electrical connectivity, and is widely used as parts of electrical and electronic equipment. This silver-coated copper material is also used as an electrical contact, and many of these electrical contacts require stable electrical connectivity. In order to stabilize the electrical connectivity, it is necessary that the contact resistance is stable both initially and over time, that the surface has good slipperiness, little wear damage, and excellent corrosion resistance.

して基材か露出すると接触抵抗が増加する。Switches are used in combination with fixed contacts and movable contacts, both of which are coated with Ag or Ag alloy. However, with this combination U, as the number of contacts increases, the operating force of the switch decreases and the contact resistance increases, reducing the life of the switch. This is due to Li adhesion between Ag and Ag, and the adhesion reduces the operating force and increases the stiffness.

潤滑効果を発揮しているものと推定される。By coating the switch with in, Qd, or an alloy thereof, it is possible to stabilize the operating force and contact resistance of the switch at low cost. In other words, adhesive wear is extremely likely to occur when Ag or A9 alloy coated substrates come into contact with each other, which reduces the operating force, and the Ag or Snake alloy layer is scraped off, exposing the substrate and increasing contact resistance. This phenomenon is prevented by coating with Sn, Pd, In, Cd, or an alloy thereof. The reason for this is not clear, but it is presumed that during the initial movement, the dissimilar metal on one side is scraped, and the scraped wear powder oxidizes, exerting a lubricating effect.
しかして／ｌ又はＡｇ合金層上の３ｎ、ｐｄ。Therefore /l or 3n, pd on the Ag alloy layer.

覆は経演上望ましくないためである。The coating thickness of In, Qd or these alloys is 0.01 to 2.
．． The reason why it is set to 0μ is because there is no effect if the thickness is less than 0.01μ, the effect is saturated if it is 2.0μ or more, and thicker coating is not desirable from the viewpoint of performance.

As is clear from Tables 1 and 3, Sn, Pd, and In were applied to the Ag-plated substrate-F. , Cd or an alloy thereof, all of the materials Nα1 to Nα9 of the present invention plated with Cd or their alloys are the comparative material Nα1.
It can be seen that the friction coefficient and contact resistance are improved compared to 0 to 13.

This seems to be due to the influence of
