摘要：
A closing edge safety device that consists of a safety strip (1) that has an electric switching device which is made up of a plurality of contact elements (2) that are arranged next to each other in a flexible tube (3). The contact elements (2) can be magnetized, an expander chord (5) can pass through them or they can lie on top of each other as a result of their weight, whereby they are urged to abut one another. When contact between one or more of the contact elements is broken, a signal is generated.
