ある。Recently, for the purpose of saving expensive precious metals, for example, a thin plate of precious metal is integrally fixed to the top surface of a strip-shaped metal piece (copper, copper alloy) by brazing, active pressure bonding, etc. A noble metal layer is formed, the metal piece is cut into chips, and the chip is used as a contact and is fixed by caulking or other means to the tip of a metal spring piece, and the contact (only the electrically contacting part on the top surface is the precious metal layer) is connected to the tip. Furthermore, progressing from the above-mentioned technology, it is possible to place precious metal thin plates, wires, etc. in arbitrary shapes and thicknesses in arbitrary positions on metal plates, pieces, etc., mainly for electrical purposes. Technologies are being developed one after another that allow precious metals to be bonded together and freely exhibit their electrical properties.

1II+) metal thin plate l (e.g. phosphor bronze thin plate), noble metal (kls ”s) is applied to the side end surface (e.g. 0.1 wa)
A material plate A is provided in which a straight precious metal side end 3 is formed by integrally fixing alloys of these materials, and a set angle (
For example, 30° to 60° (any angle other than a right angle)) Cut the material plate A into strips at an angle to form a contact spring piece having an inclined precious metal side end 3 at the tip. Then, insert the vicinity of the tip of the contact spring piece into its precious metal side end 3.
A contact spring piece B of a leaf switch is manufactured by bending the leaf switch at right angles in parallel with the leaf switch, and using the noble metal side end 3 of the bent tip as the contact point P.

A leaf switch is constructed by embedding P in an appropriate insulating base φ with the contacts facing each other and both contacts in contact (normally closed type leaf switch) or separated (normal oven type leaf switch). (Figure 3) At that time, the contacts P%P of each contact spring piece B%B are always inclined at the set angle due to the above configuration, so the opposing contacts P%P must be crossed obliquely. Face-to-face separation (by turning the switch ON and OFF) results in an advantage that, for example, even if the installation positions of the contact spring pieces B and B are slightly misaligned, the contacts can always reliably contact and separate from each other.

When the contact spring pieces 17F are installed facing each other, since the plate thickness of the contact spring pieces is extremely thin (as described above, e.g. Unless the positions of the contacts are adjusted very precisely, it is not possible to accurately connect and separate the contacts, but if the contacts are arranged diagonally across each other as in the present invention, the installation of the contact spring pieces will be easier. Even if there is an error in position, the contacts can always move toward and away from each other accurately without any adjustment, and this is a remarkable feature of the present invention.

し得るものである。(3)...Furthermore, according to the present invention, there is an advantage that the contact spring pieces of the present invention can be continuously mass-produced in large numbers from the hoop-shaped material plate A. A completed contact spring piece can be manufactured immediately by simply press cutting and bending, so as in the past, after forming the contact spring piece by appropriate press cutting, etc., the tip of the contact spring piece is On the other hand, caulking a separate contact eliminates the process of attaching it by processing or other means, and also significantly reduces the manufacturing process, material cost, processing cost, etc. for forming the contact itself. Simplify and
In addition to cost reduction, it is possible to exhibit excellent effects that lead to improved productivity of leaf switches, cost reduction, etc.
