Product Description

• The EAO 51-282.0252F is an industrial maintained-action pushbutton switch from the EAO Series 51 product family, designed for installation in compatible industrial control panels, machinery, and electrical equipment.
• The actuator features a snap-action switching mechanism with two normally open and two normally closed contacts. Its maintained operation allows the switch to remain in its selected switching state until operated again, unlike a momentary pushbutton that returns automatically when released.
• This particular assembly includes a blank, unmarked dark-colored button face without printed lettering or symbols. The button is directly accessible and is not equipped with a transparent hinged protective cover.
• The assembly includes the attached switch contact elements, panel-mounting components, and a gray wiring harness. The individual conductors retain their crimped wire ferrules and identification markers for connection to compatible equipment.
• EAO specifies the 51-282.0252F with gold contacts and solder terminals. The actuator has a switching rating of 3 A at 250 VAC with solder terminals. Other AC and DC ratings depend on the applicable load and operating conditions.
• The manufacturer specifies IP65 front-panel protection when correctly installed, an operating temperature range of -25°C to +55°C, and a mechanical lifetime of up to 1,000,000 operations under specified conditions.
• The Series 51 actuator supports illuminated configurations, although the presence and functionality of a lamp in this assembly have not been independently verified.
• This unit was sourced from a new, uncommissioned equipment cabinet that was dismantled before being placed into service. The switch and attached wiring have not been independently functionally tested.
• The blank button face does not identify a particular control function. Buyers should confirm the contact arrangement, maintained switching action, mounting dimensions, and wiring assignments before installation.
