There is a conventional mat type switch that returns to a non-conducting state (OFF) when separated. One example is shown in FIG. This is such that a support F made of an insulating rubber sheet is arranged between an upper sheet D in which a conductive rubber B is attached below an insulating rubber A and a lower sheet E made of metal, and the conductive rubber B and the lower sheet E are normally placed. E is separated from the support F by the support F and is in a non-conductive state. When a person rides on the upper sheet D, the upper sheet D is deformed and the conductive rubber B is a space G between the supports F adjacent to each other.

検出してしまうといった難点があった。In the mat type switch shown in FIG. 6, when a person rides on the upper sheet D, the sheet D is deformed to be in a conductive state, so that it does not step right above the space G. If it is directly above the space G, even if it is a person other than a human being, such as a dog or a cat, it may be in a conductive state. For this reason, there are drawbacks such that the human does not operate even when stepped on, and the intruder of a human being should be detected, but the intruder of a dog or a cat is detected.

In this case, for example, one or several large mat switches may be laid, or a large number of mat switches 20 each having a size of several tens cm may be laid. At this time, the mat switch 20 is set so that, for example, when a person weighing 30 kg or more rides on the upper substrate 1, the conductive surface of the same substrate 1 comes into contact with the conductive surface of the other substrate and is turned on. When a load of 30 kg or more is applied to the mat switch 20, the mat switch 20 is turned on and the situation is detected.

ることもできる。The mat switch according to claims 1 to 6 of the present invention has the following effects. . Since the boards 1 and 2 are rigid, they do not locally bend or deform even when stepped on by a person, so they do not operate even when stepped on by small animals or lightweight children, and do not turn on unless a predetermined load is applied. Therefore, if the load to be turned on is set according to the detection target, it is possible to reliably detect only the desired load or more, and there is no malfunction such as accidentally detecting a light load. . Since the substrates 1 and 2 are rigid, when a load is applied to the substrate 1, the entire substrate 1 approaches the substrate 2 without locally bending or deforming the substrate 1. Therefore, a person having a predetermined weight or more can surely turn on regardless of where on the substrate 1. . Not only can a suspicious person be detected, but it can also be used at the entrance of a store to detect the entrance and exit of a customer, and can be used for sorting packages.
