Abstract (en)
[origin: CA3221892A1] A monitoring system for an optical display element of an emergency stop switch, the monitoring system comprising an actuation element with optical display element, an optical sensor and safety electronics. The safety electronics are connected to the optical display element and the optical sensor. The safety electronics comprise a safe output and a safe input and are connected to the optical display element via the safe output and to the optical sensor via the safe input. As a result, it is possible to ensure that the optical display element functions reliably, or is not defective, in order to avoid fatal consequences for life and limb. The optical display element can comprise a single display element or a plurality of display elements.
