行なうように構成されていた。As shown in Fig. 1, a conventional switch using pressurized conductive rubber has a contact pattern 1 on one side, a through hole 2 in a part, and a conductive pattern 2 to -7 73 on the other side. Using a through-hole printed circuit board 4, a pressurized conductive rubber 6 was placed on the side where the contact pattern 1 was provided, and the pressurized conductive rubber 6 corresponding to the contact portion was pressurized to perform switching.

パターンのみのプリント基板に対してコスト面で著しく
高くカリ、実用化を計る上で大きな障害となっていた。In this configuration, as a keyboard switch with high mounting density, it is necessary to use a through-hole printed circuit board 4 as described above, and this through-hole printed circuit board 4 is significantly more expensive than a printed circuit board with only a single-sided pattern, and is not practical. This was a major obstacle in the way of expansion.
本発明は以上のような従来の欠点を除去するものであり
、安価なスイッチを提供しようとするものである。The present invention aims to eliminate the above-mentioned conventional drawbacks and provide an inexpensive switch.
以下、本発明の実施例を図面第２図によシ説明する。Embodiments of the present invention will be described below with reference to FIG. 2 of the drawings.

安価なものとなり、実用性に富んだものとなる。As described above, the switch of the present invention has a conductive layer on the pressurized conductive rubber sheet or the housing, and a pressure protrusion on the nozzle, so it can be used as a printed circuit board with a contact pattern formed on one side. Kaisho 59-20922
3(2) can be used, making it significantly cheaper than that using a through-hole printed circuit board, making the switch inexpensive and highly practical.
