Abstract (en)
[origin: EP1037234A2] The safety cut-out switch has at least 2 series opening switches (12a,12b,12c) coupled to a microprocessor evaluation unit (11), for providing a safety signal, e.g. an alarm or cut-out signal, upon opening of at least one of these switches, which each have a code signal generator (13a,13b,13c), coupled to the evaluation unit via a common diagnosis line, for providing a code signal identifying the operated switch.
