Abstract
A data-recording machine is protected against temperature overshoots by a device (12) for protecting electrical lines comprising two blister-type thermosensitive elements (10C, 10F) which control series-connected electric contacts (7C, 7F) so as to close the electrical line outside the normal operating range and to prohibit operation even after a return to said range.
