A conductive contact member is formed on the back surface of the top. Its usage is to push each key top and move the corresponding contact member to turn on / off the fixed contact on the printed circuit board side. The contact members are roughly classified into carbon contacts and metal contacts. The carbon contact has a relatively high electric resistance and is used at, for example, DC24V and 30mA, whereas the metal contact has a low electric resistance and is used at, for example, DC24V and 100mA for automobile back mills, and for automobile power windows. Used at DC24V, 800mA.

A primer treatment is applied to the back surface of the nickel plate on the side opposite to the surface subjected to the above.
Then, the surface of the nickel plate on the primer-treated side and the silicone rubber material are overlaid and baked in a mold to form a plate. This plate-shaped molded product is punched into a circular shape with a press to obtain a metal contact. This circular metal contact is set in the lower mold with the gold-plated side facing down and the silicone rubber side facing up, and silicone raw rubber is placed on top of it and pressed, and the primary mold is pressed with the upper mold. Vulcanization and secondary thermal vulcanization are performed to obtain a silicon rubber pad with metal contacts.

良の原因ともなっていた。According to the above-mentioned conventional method for manufacturing a metal contact, the contact is made by separate firing, and when the contact is mounted in the mold, the direction of the contact is set (the gold-plated side is set downward). We had to be careful and had the drawback of being very poor in productivity. Further, the conventional metal contact has a drawback that the contact portion is not flexible because a metal plate is used. In particular, metal contacts using metal plates are not flexible, so if dust or foreign matter adheres to the contacts,
Due to repeated on / off operations and the like, the metal plate of the contact portion is deformed into a state of being dented by the amount of foreign matter, etc., and that portion of the metal plate remains dented and does not restore, which is also a cause of malfunction of the contact portion.
