1, Y 2 and outer body 2 having waterproof continuous direction), and also has a Y 1, Y 2 long continuous direction space 3 in the outer body 2. The exterior body 2 does not particularly limit whether or not it has waterproofness. As shown in FIG. 2, the space 3 is formed of a first material made of, for example, a polyimide material formed on both ends of the space 3 of the exterior body 2.
An insulating layer 4, a lower electrode 5 made of a conductive material disposed below the first insulating layer 4 below the space 3, and disposed above the first insulating layer 4 above the space 3. And an upper electrode 6 made of a conductive spring alloy such as phosphor bronze disposed in a state facing the lower electrode 5. Inside the exterior body 2, along the inner wall surface, that is, the inner wall surface of the hollow portion of the exterior body 2,
A second insulating layer formed so as to cover the entirety of the lower electrode, the insulating layer, and the upper electrode in the longitudinal direction. Therefore, both ends in the length direction of the upper side of the lower electrode 5 are covered with the first insulating layer 4, the remaining portion of the upper side of the lower electrode 5 is exposed as a contact portion, and the lower surface of the upper electrode 6 and the minute gap 7 are exposed. , And constitute a switch unit. It goes without saying that the exterior shape of the exterior body 2 can be variously modified, such as a dish-shaped cross section, a semicircular cross section, and a trapezoidal cross section, in addition to the shapes described above. According to the long switch 1 of the present embodiment, the lower electrode 5 is opposed to the lower surface of the upper electrode 6 using a spring alloy via the minute gap 7, and these are brought into contact with or separated from each other depending on the presence or absence of a load. Therefore, the conduction resistance between the lower electrode 5 and the upper electrode 6 is smaller than that of the conventional example described above, and the response speed with respect to a load change can be increased, thereby improving the electrical characteristics of the switch. Can be planned. Further, when the variation of the load operating pressure of the long switch 1 according to the present embodiment was measured, it was possible to suppress the variation to a predetermined representative value of + 20% and -20%, and to improve the variation characteristic of the operational sensitivity. It turns out that it can be planned. In addition, it was confirmed by experiments that the waterproof property was equivalent to JIS C09207 class. As described above, according to the long switch 1 according to the present embodiment, the response speed can be increased, the electrical characteristics can be improved, and a wide range of waterproof environments from drip-proof to anti-invasion can be supported. It can be used as a sensing element for measurement. That is, the long switch 1 of the present embodiment detects the presence of a person in the vicinity of a machine tool, a robot, or the like to prevent danger, or a person or a moving object (door opening / closing, automatic shutter, automatic guided vehicle, etc.). To detect an emergency signal, to detect the presence of a person or moving object, to measure the elapsed time from the starting point to the ending point, and to detect intruders into houses, etc. It can be applied to various wide-ranging uses such as generating a security signal or the like.
