Summary

• The EAO 51-282.0252F Series 51 pushbutton switch assembly features a maintained-action switching mechanism with 2 normally open (NO) and 2 normally closed (NC) contacts. This industrial panel-mount assembly includes a blank, unmarked dark-colored pushbutton, transparent hinged protective cover, attached switch contacts, mounting components, and a prewired gray wiring harness with labeled conductors and crimped wire ferrules.
• Unlike the STOP-labeled configuration, this assembly features a blank button face without lettering or symbols. The transparent protective cover can be lifted to access the button and helps reduce unintentional operation. The attached wiring provides connections for installation in compatible industrial control panels and equipment.
• This item was sourced from a new, uncommissioned equipment cabinet that was dismantled prior to being placed into service. Please review all photos for the exact item, condition, and components included.

Product Description

• The EAO 51-282.0252F is an industrial maintained-action pushbutton switch actuator from the EAO Series 51 product family. It is designed for integration into compatible electrical control panels, machinery, operator interfaces, and industrial equipment.
• The actuator features a snap-action switching system with two normally open and two normally closed contacts. Its maintained-action mechanism is designed to retain its selected switching state after actuation, rather than automatically returning like a momentary-action pushbutton.
• This particular assembly is fitted with a blank, unmarked dark-colored pushbutton face and a transparent hinged protective cover. The cover opens to provide access to the pushbutton while serving as a physical barrier when closed.
• The hinged cover includes an adjacent metal component that forms part of the installed protective-cover assembly. The exact manufacturer part number and intended function of this component have not been independently verified.
• The assembly includes black panel-mounting components, attached electrical contacts, and a gray wiring harness. The conductors are terminated with crimped wire ferrules and identification markers for integration into compatible equipment.
• EAO specifies the 51-282.0252F actuator with gold contacts and solder terminals. The manufacturer's electrical specifications include a 3 A switching rating at 250 VAC using solder terminals, with other AC and DC ratings dependent on load characteristics.
• The manufacturer specifies IP65 front protection when correctly installed, an operating temperature range of -25°C to +55°C, and a mechanical life of up to 1,000,000 operations under specified conditions.
• The actuator is part of EAO's configurable Series 51 system. Although the actuator supports illuminated configurations, an installed lamp, its voltage, and working illumination have not been verified on this assembly.
• This item was removed from a new, uncommissioned equipment cabinet before the cabinet was placed into service. Functional operation of the switch and continuity of the attached wiring have not been independently verified.
• The blank button face does not indicate a specific control function. Buyers should confirm the contact configuration, maintained-action operation, installation requirements, and individual wiring connections before use.
