EAO 61-8490.22 is a snap-action switching element featuring a configuration of one normally closed (NC) and two normally open (NO) contacts, constructed with a combination of gold and silver materials for the contact surfaces. This configuration provides reliable switching with low resistance and durable performance, suitable for both signal and power applications. Typical engineering applications include use in control panels, industrial automation systems, and other environments where precise and rapid switching actions are essential.
