CA 2260012

A tubular switch which is normally off, instantaneously turned on by an external pressure, and has a long detecting distance. The switch comprises a hose member (11) having an insulating property and an elasticity and a plurality of flexible conductive members (12) which are spirally fixed to the internal surface of the member (11) so that the surfaces of the members (12) can be exposed partially to the internal space of the member (11) over the whole cross sections of the member (11). The switch has durability, a simple structure, and flexibility, can be installed to any place,and has a long detecting range. In addition, the fault of the switch is easily found, repaired, and adjusted and the switch is manufactured at a low cost.

La présente invention concerne un commutateur tubulaire qui normalement ouvert et se fermant instantanément sous l'effet d'une pression externe. Ce commutateur tubulaire, caractérisé par une longue portée de détection, est constitué, d'une part d'un élément en forme de tuyau (11) isolant et élastique, et d'autre part d'une pluralité d'éléments électroconducteurs souples (12) spiralés de façon fixe contre la face interne de l'élément en forme de tuyau (11) de façon que les surfaces des éléments électroconducteurs (12) puissent être partiellement exposés au volume intérieur de l'élément en forme de tuyau (11) sur la totalité des coupes transversales de l'élément en forme de tuyau (11). Ce commutateur est caractérisé par sa bonne durée de vie, sa simplicité de structure, sa souplesse d'emploi, son aptitude à se monter n'importe où, et sa longue portée de détection. De plus, les incidents affectant le commutateur se trouvent, se réparent et se corrigent facilement, le commutateur étant bon marché à fabriquer.
