The device includes a switch arrangement which comprises a number of contact elements (1) strung together along the safety arrangement by device of a guide device (2), and are compressed through an axial tension along the safety arrangement. Each contact element comprises contact zones (3) which are electrically inter-connected within the respective contact element, and which form at rest electric contact to adjacent contact elements (14) towards both sides. The electric contact is broken at bending of the switch arrangement through external pressure (5). The tension is produced through tube pieces (2) which overlap in alternating sequence with respectively two contact elements, and which press respectively the contact zones of the overlapped contact elements (1,1') against each other. |
