するという問題があった。A diaphragm 3 made of a conductive material that is activated by the operation of a push button 2, and a fixed contact S that is electrically connected and disconnected via this diaphragm 3, the fixed contact S is
It has generally been formed of a first contact 4 that comes into contact with and leaves the center of the diaphragm 3, and a second contact 5 that comes into contact with the periphery of the diaphragm 30. However, with this configuration, if water gets inside the switch, the electrical insulation performance is insufficient, and there is a problem that the control section of the fl microcomputer, etc., which is operated by the operation of the switch, may malfunction. there were.
発明の目的
本発明はこのような従来の問題を解消し、電気的絶縁性

周辺部が接したリング状の第２の接点１１とよりなる。Embodiment Song f Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In FIGS. 2 and 3, 6 is a base made of an insulating material such as resin, 7 is a push button that is loosely inserted into the insulating base 6, and 8 is activated by the operation of the loosely inserted/push button. A diaphragm made of conductive material. The insulating base 6 has a fixed contact 9 that is turned on and off via the diaphragm 8 by the operation of the diaphragm 8, and this fixed contact 9 is in contact with the center of the diaphragm 8 by 1qlG. First contact 10 and diaphragm 80
It consists of a ring-shaped second contact 11 whose periphery is in contact.
また、基台６には、第１の接点１０と第２の接点１１と
の間に位置して略環状の溝部１２を形成している。Furthermore, a substantially annular groove portion 12 is formed in the base 6 and located between the first contact point 10 and the second contact point 11.

、第１、第２の接点１ｏ、１１間の絶縁性能をきわめて
良好に維持できる。To explain the operation in the above configuration, when push button 7 is pressed,
A diaphragm 8 made of a conductive material contacts both the first and second contacts 10.11 to establish electrical continuity. Here, when water enters the inside of the switch or dew condensation occurs inside the switch, the water accumulates in the groove 12, and moreover, the first. The insulation creepage distance between the second contacts 10 and 11 is increased due to the presence of the groove 12.
, the insulation performance between the first and second contacts 1o and 11 can be maintained very well.
発明の効果
上記実施例からあきらかなように本発明によれば、溝部

るために、スイッチの誤動作を未然に防止できる。Effects of the Invention As is clear from the above embodiments, according to the present invention, even if water enters the inside of the switch, due to the presence of the groove, the first. Since the insulation distance between the second contacts is large, malfunction of the switch can be prevented.
