EAO 51-261.022 is an illuminated pushbutton featuring both a single normally closed (NC) contact and a single normally open (NO) contact configuration. This component is distinguished by its precision-engineered switch mechanisms, ensuring reliable operation in both signalling and control applications. The device measures 18x24 millimetres and incorporates gold and silver contacts, which provide enhanced conductivity and resistance to corrosion, making it suitable for demanding environments. Typical applications for this illuminated pushbutton include industrial control systems.
