本発明は加圧導電ゴムをスイツチ素子として用
いたスイツチに係り、安価なものを提供しようと
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a switch using pressurized conductive rubber as a switch element, and aims to provide an inexpensive switch.

を加圧してスイツチングを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 includes a through-hole printed circuit board 4 with a contact pattern 1 on one side, a through-hole 2 formed on one part, and a conductive pattern 3 formed on the other side.
The pressurized conductive rubber 5 is placed on the side where the contact pattern 1 is provided, and the pressurized conductive rubber 5 corresponding to the contact part is placed on the side where the contact pattern 1 is provided.
It was designed to perform switching by applying pressure.

プリント基板４は片面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なり、実用化を
計る上で大きな障害となつていた。 In this configuration, as a keyboard switch with high mounting density, it is necessary to use the through-hole printed circuit board 4 as described above, and the cost of this through-hole printed circuit board 4 is significantly higher than that of a printed circuit board with only a single-sided pattern, so it is not practical. This has been a major obstacle in the way of achieving this goal.
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、安価なスイツ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図により説明

会社製のものを用いる。 A printed circuit board 6 has a contact pattern 7 formed on one side by a method such as printing, and a pressurized conductive rubber sheet 8 is placed on the surface of the printed circuit board 6 on which the contact pattern 7 is formed. This pressurized conductive rubber sheet 8 is made by Japan Synthetic Rubber Co., Ltd. and is made of silicone rubber with nickel powder arranged at certain intervals in the vertical direction.

などの導電層１２が設けられている。 A housing 10 made of an insulating material and having a window 9 for pressurizing the pressurized conductive rubber sheet 8 corresponding to the contact portion of the contact pattern 7 is disposed on top of this, and the pressurized conductive rubber sheet 8 of this housing 10 is disposed. A protrusion 11 is provided at a portion where it is desired to conduct between the side contact patterns 7, and a conductive layer 12 such as metal foil is provided between the protrusions 11.
すなわち、この突部１１によつて加圧導電ゴム

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 pressurizing protrusion on the housing, so a printed circuit board with a contact pattern formed on one side can be used. This makes it significantly cheaper than those using through-hole printed circuit boards, making the switch inexpensive and highly practical.
