A protected closed space (L) comprises at least one wall element (E) provided with an electrical interruptor (C1, C2) in turn protected by a thin and flexible probe (S, B) which on the one hand transmits the external mechanical control movement (P) and on the other hand permits the detection of an intrusion at this weak point of the protected closed space. Application: protected closed space with key-board for providing the access code, especially for an electronic payment system. |
