い得ることは勿論である。This tape-shaped composite contact material is intermittently fed by a grip feeder, and an arrowhead-shaped notch extending in a direction perpendicular to the longitudinal direction of the tape is formed every 2.0 mm in the longitudinal direction of the tape at a rate of 100 per minute. The stamp was engraved on the tape. The depth of each notch was 0.32+am, and the convergence angle was 30 degrees. The tape was then cut into individual contact pieces at the tip of the notch. In this case, the depth of the arrowhead-shaped notch may be increased, and the tape may be cut to a predetermined length ψ at the same time as the notch is formed.Also, in this example, pure silver was used for the contact surface. is Ag-N i ,Ag
Of course, various silver alloys such as -Cd0 and Ag-3n02 alloys can be used.

るのにより好適であることも勿論である。In addition, by making the protruding portion extending to the lower side of the contact surface narrower than the contact surface and making the cross section of the entire long tape-shaped composite electrical contact material T-shaped, a rivet-shaped contact piece for crimping can be manufactured. Of course, it is also more suitable for
（ホ）発明の効果 本発明の方法は、接点面が銀合金である場合。(e) Effects of the invention The method of the present invention applies when the contact surface is a silver alloy.
特にＡｇ−Ｃｄ０ 、Ａｇ−３ｎ０２等の金属酸化物を
含む銀合金の場合には、独特の効果がある。In particular, silver alloys containing metal oxides such as Ag-Cd0 and Ag-3n02 have unique effects.

に変形せしめると、クラックが生じることが屡々ある。That is, although such silver alloys have excellent fire resistance,
Because of its high hardness, unlike the copper alloy that forms the base, it is not uncommon for cracks to occur when deformed. Cracks often occur when the wire piece for the contact surface is flattened after joining the short wire piece that will serve as the base for caulking.
ところが、この発明にあっては、接点面をなす銀合金は
テープ状の複合電気接点材のｔ面をなし、もともと扁平
であるので、格別の変形を要しないで、従ってクラック
が生じる虞れなしに単体接点片が得られるのである。However, in this invention, since the silver alloy forming the contact surface forms the t-plane of the tape-shaped composite electrical contact material and is originally flat, no special deformation is required, and therefore there is no risk of cracks occurring. A single contact piece can be obtained.
