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 gray wiring harness.
• IMPORTANT: The attached wiring harness has been cut just above the original wire-end terminals. The leads are supplied without their original crimped ferrules or connectors and will require appropriate preparation and termination before installation.
• This assembly does not include a transparent hinged protective cover. The STOP pushbutton is directly accessible.
• This item is listed as New Old Stock (NOS) because it was sourced from an uncommissioned cabinet. However, the cut wiring is a modification to its original configuration and is clearly disclosed. The switch has not been functionally tested.
• 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 integration into compatible electrical control panels, machinery, and operator-interface systems.
• The actuator features a snap-action switching mechanism with two normally open and two normally closed contacts. Unlike a momentary pushbutton, its maintained-action mechanism retains its selected switching state until operated again.
• This particular assembly features a dark-colored pushbutton with the word STOP printed on the button face. There is no transparent protective cover included with this configuration.
• The assembly includes black panel-mounting components, electrical contacts, and an attached gray wiring harness. The wire ends have been cut just above their original terminals, leaving the leads without the original ferrules or connectors.
• The wiring has not been reterminated or repaired. Buyers should inspect the photographs carefully and verify that the remaining wire length and lead arrangement are suitable for their installation.
• 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 using solder terminals, with other ratings dependent on the electrical load and operating conditions.
• The manufacturer specifies IP65 front-panel protection when properly installed, an operating temperature range of -25°C to +55°C, and a mechanical operating life of up to 1,000,000 operations under specified conditions.
• The Series 51 actuator supports configurable illuminated installations. However, the presence, voltage, and operating condition of a lamp in this assembly have not been verified.
• This switch was sourced from a new, uncommissioned equipment cabinet dismantled before entering service. Although the switch was not placed into service, its attached wiring was cut during removal.
• The cut wiring is the reason this assembly is being offered at a reduced price. Functional operation and electrical continuity have not been independently tested.
• The STOP button marking does not independently establish that the assembly is certified for use as a safety-rated emergency-stop device. Buyers should verify switching requirements, circuit ratings, wire assignments, and installation suitability before use.
