Blue backlit flush-mount button 1 NO 1 NC nickel ring "ON" ST22-KLN-11-230-LED\AC-5/CZ

Control button – reliability and functionality in one

This critical, backlit control button is a solid solution for applications requiring reliable operation and clear signaling. Equipped with a blue LED, it provides clear identification even in low light conditions. The front ring made of plastic, in nickel color, adds to its aesthetic appearance and resistance to damage. The button is designed for mounting in 22 mm diameter holes and is characterized by a high degree of protection IP65, which guarantees its safe use in harsh industrial conditions.

Construction and user parameters

The button has one normally open (NO) and one normally closed (NC) contact, making it a versatile element in control circuits. Its construction has been designed for long-term operation – it withstands as many as 3 million mechanical switching cycles and 0.2 million switching cycles at rated parameters. Vibration and shock resistance, in accordance with IEC 60068-2-6 and IEC 60068-2-27 standards, confirms its reliability in demanding industrial environments. A wide operating temperature range (-40°C to +70°C) allows its use both indoors and outdoors.

Application and compliance with standards

This button finds application in a wide range of devices and machines, such as control panels, electrical cabinets or industrial automation devices. It meets the requirements of PN-EN 60947-5-1 and IEC 60947-5-1 and IEC 60947-1 standards, which guarantees its safety and compliance with applicable regulations. The possibility of connecting wires with a cross-section from 1 to 2.5 mm² (solid) or from 0.75 to 1.5 mm² (stranded) ensures easy integration with the existing electrical installation. In addition, the rated insulation voltage U i is as high as 500 V and the rated continuous current I u=I th is 10 A.
