Summary

• The EAO 51-282.0252F Series 51 STOP 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 dark-colored STOP-labeled pushbutton, attached switch contacts, mounting components, and a prewired gray wiring harness with labeled conductors and crimped wire ferrules.
• This version does not include the transparent hinged protective cover found on some other EAO Series 51 assemblies. The STOP button is accessible directly without opening a cover.
• 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, designed for installation in compatible industrial control panels, machinery, and operator-interface equipment.
• The switch uses a snap-action switching mechanism featuring two normally open and two normally closed contacts. Its maintained-action operation allows the switch to retain its selected state after actuation until operated again.
• This assembly features a dark-colored pushbutton with the word STOP printed on its face. Unlike other configurations of the same actuator, this version does not have a transparent hinged protective cover.
• The assembly includes the original attached contact and terminal components, black panel-mounting hardware, and a prewired gray wiring harness. The individual leads terminate in crimped wire ferrules with identification markers, as supplied with this assembly.
• EAO specifies the 51-282.0252F actuator with gold contacts and solder terminals. The manufacturer's documented electrical ratings include 3 A at 250 VAC with solder terminals, with other AC and DC switching ratings dependent on the load.
• The manufacturer specifies IP65 front-panel protection under proper installation conditions, an operating temperature range of -25°C to +55°C, and a mechanical lifetime of up to 1,000,000 operations.
• Although the Series 51 actuator supports illumination configurations, the presence and operation of a lamp in this particular assembly have not been verified.
• This unit was sourced from a new, uncommissioned equipment cabinet that was dismantled before entering service. Functional operation and the attached wiring have not been independently tested.
• The STOP marking identifies the pushbutton legend but does not independently establish emergency-stop safety certification. Buyers should confirm the applicable contact ratings, switching action, mounting requirements, and wiring configuration before installation.
