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 pushbutton, attached contact and mounting components, and a gray wiring harness.
• IMPORTANT: The wiring harness has been cut just above the original wire-end terminals. The original ferrules or connectors are missing, leaving the wires unterminated. The buyer will need to prepare and terminate the leads before installation.
• This assembly has no lettering or symbols on the button face and does not include a clear hinged protective cover.
• This item is being offered as New Old Stock (NOS) because it was sourced from an uncommissioned cabinet. However, the attached wiring has been altered during removal, and the missing wire-end terminals are disclosed as part of the item's condition.
• 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 electrical equipment.
• The actuator features a snap-action switching mechanism with two normally open and two normally closed contacts. Its maintained-action operation allows the switch to remain in its selected switching state until operated again.
• This configuration includes a blank, unmarked dark-colored pushbutton with no lettering or symbols. The button is directly accessible, as there is no clear hinged protective cover included.
• The switch includes its attached contact assembly, panel-mounting components, and a gray wiring harness. Unlike the otherwise identical configuration with original terminals, this unit has had its wire ends cut just above the original ferrules or connectors.
• The cut wire ends remain unterminated. The original wire-end terminals are not included, and the harness has not been repaired or reterminated. Buyers should verify the available wire length and suitability for their intended installation.
• EAO specifies the 51-282.0252F actuator with gold contacts and solder-terminal connections. The manufacturer's documented switching rating is 3 A at 250 VAC when using solder terminals. Additional AC and DC electrical ratings depend on the connected load and circuit 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, but the presence and functionality of an installed lamp have not been verified for this particular assembly.
• This item was sourced from a new, uncommissioned equipment cabinet dismantled before the cabinet was placed into service. Although the switch was not installed in operating equipment, the attached wiring was cut during removal.
• The wiring modification is the reason this assembly is offered at a reduced price. Functional operation and electrical continuity have not been independently tested.
• The blank button face does not establish a specific control function. Buyers should verify the maintained switching action, contact configuration, available wire length, and installation requirements before purchase.
