The Cobra foot-operated safety switches consist of two system components: foot-operated switch and protective cover. The various different technical features include all contacts' positive opening operation and a pressure point element integrated under the pedal, which when the pedal is sharply pushed down triggers an immediate stop of the machine. The housing design of both system components has been defined in such a way that combining two or more switches side by side creates compact foot-operated switch blocks that form a neatly shaped unit. A core innovation and unparalleled in the field of industrial foot-operated safety switches is the use of an extruded aluminium protective cover that doesn't break even under heavy impact and thus protects the foot from injury. The cover also provides protection from accidental activation.
