この場合、くさび要素はくさび板として形成され、接点要素は接点板として形成

るがしかし、小さな負荷で開閉接点が開放する。[0002] EP-A-0421048 describes a safety strip used as an opening / closing mat. In this case, a number of contact elements and wedge elements are provided. The contact element and the wedge element are pulled together by the expansion cord.
In this case, the wedge element is formed as a wedge plate, the contact element is formed as a contact plate, and when ready for opening and closing, the expansion cord is at a different height position in the contact plate and the wedge plate. With this arrangement code, an opening / closing mat that can be extended over a relatively large range is formed. This mat can be run over by the vehicle without any problem, but the switching contact opens with a small load.

ット全体内の１つの故障がマット全体を使用不可能にし、この機能不良が認識困
難であるという欠点がある。That is, in the case of this opening / closing mat, the opening / closing elements are connected by an expansion cord over a large surface area, and the opening / closing elements are not formed as individual safety switches independent of each other. Yes, thereby having the disadvantage that one failure in the entire mat renders the entire mat unusable, and that this malfunction is difficult to recognize.

ストロークがしか必要としない。[0004] The opening and closing mat described in EP-A-0421048 is furthermore difficult to easily adapt to the very different shapes that are common in practice. In contrast, DE-A-43 19 386 proposes a safety switch which, in operation, for example, interrupts a closed-circuit current or otherwise switches an electrical switching circuit. In this case, only a small opening and closing stroke is required to open and close.

形に適合させることができる。On the other hand, the problem underlying the present invention is to provide an opening and closing mat with a safety switch which itself forms one unit. In this case, the safety switches can be connected to one another. Thereby it can be adapted to various shapes using the safety mat.

イッチのない領域を設けることができる。This problem underlying the invention is solved by the features of claim 1. Advantageous embodiments are set out in the dependent claims. In other words, many individual safety switches, which themselves form one unit, can be connected to one another. In this case, the individual safety switches can be clipped to one another, for example. Thereby, an opening / closing mat of any shape can be formed. In this case, for example, the individual safety switches, which themselves form a unit, are arranged in a plate-shaped mat, which has at least one upper coating layer and a lower coating layer. This mat can be adapted to the desired shape. The mat can be provided with an area without a safety switch.

してある。Next, an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, two safety switches located in the mat are indicated by 1 and 2. In this case, the mat has an upper coating layer 3 and a lower coating layer 4.
The switches 1, 2 are movable under load against the return forces of the spring elements 5, 6. Electrical contacts 9 and 10 are provided in casings 7 and 8 of the switches 1 and 2, respectively. This contact is provided with electrical contacts 9a, 1 provided in mushroom-shaped pressing bodies 11, 12.
Work with Oa. The conductive lines in the mushroom-shaped pressing bodies 11, 12 are indicated by 14, 15.
【０００９】 更に、明示するために、電流回路Ｉのための給電線１６，１７と、電流回路Ｉ

Feed lines 26 and 27 for I are marked. The lower part of FIG. 1 shows a state in which the mushroom-shaped pressing bodies 11 and 12 are pushed downward by a load, the contacts 10, 10a or 9, 9a are cut off, and the switching contacts are opened.
【００１０】 図２から明らかなように、異なるように形成された安全スイッチを互いに接続

っている。導線２６，２７によって、第２の電流回路が形成される。As is evident from FIG. 2, differently formed safety switches can be connected to one another. In this case, in particular, the safety switch 18 differs from the rectangular shape of the other three safety switches in order to demonstrate that a different shape adaptation is possible. The conductors 26 and 27 form a second current circuit.

Example I shows a simple triangle, and Examples II, III, IV show that differently shaped plates can be joined together and thereby adapted to the desired shape. An opening / closing mat is provided in this shape.

全スイッチによって覆われない空間が発生し得る。The figures do not show that the individual safety switches can be fixedly connected to one another, for example that they can be clipped. Due to this connection, when the safety switch is placed in the mat formed by the upper cover layer 3 and the lower cover layer 4, sliding of the safety switch is impossible. This may create a space that may not otherwise be covered by the safety switch.
