The Powerful R series 19 mm pushbuttons make pilferage difficult. Control panels were never so strong even in complex industrial locations and exposed public venues (protected to IK09 and IP65). Superb stainless steel, brass and nickel-plated brass make them what they are. The domed actuator switches 1NO either with pin terminal or screw terminal. These great pushbuttons find a place at access controlled security systems and in industrial machinery and factory equipment. Exposed areas need pushbutton security like at kiosks, vending and ticketing machines, almost everywhere.
