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 pushbutton, transparent hinged protective cover, attached switch contacts, mounting components, and a prewired wiring harness with labeled conductors and crimped wire ferrules.
• The hinged transparent cover can be lifted to access the STOP button and provides a physical barrier to help reduce unintended operation. The attached wiring harness allows integration into compatible industrial control panels and equipment, subject to verification of the original wiring configuration.
• 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.
• This is a multiple quantity listing and the unit that you will receive may be different than the unit shown, but is in the same cosmetic condition. Please review all photos for the exact item, condition, and components included.

Product Description

• The EAO 51-282.0252F is an industrial pushbutton switch actuator from the EAO Series 51 product family, designed for integration into compatible electrical control panels, machinery, and operator-interface systems.
• The switch features a maintained-action mechanism with a 2 NO + 2 NC contact configuration. Its snap-action switching elements provide two normally open and two normally closed contacts for compatible electrical control circuits. Unlike a momentary pushbutton, a maintained-action switch is designed to remain in its selected switching state until actuated again.
• This complete assembly includes a dark STOP-labeled pushbutton and a transparent hinged protective cover. The cover can be opened to access the button while providing an additional physical barrier against accidental contact when closed.
• The installed cover includes a small metal component beside the hinge. The exact function and manufacturer part number of this additional hardware have not been independently verified.
• The actuator is equipped with gold contacts and solder terminals. Its contacts are connected to an attached gray wiring harness with individually labeled conductors and crimped wire ferrules, as shown in the photographs.
• EAO specifies the 51-282.0252F actuator for switching applications up to 250 VAC at 3 A when using the specified solder-terminal connection. Other AC and DC switching ratings depend on circuit conditions and load characteristics.
• The manufacturer specifies IP65 front-panel protection when the actuator is correctly installed, an operating temperature range of -25°C to +55°C, and a mechanical operating life of up to 1,000,000 cycles under specified conditions.
• The manufacturer's Series 51 product family is designed for industrial control applications where compact panel mounting and clearly identified operator controls are required.
• The STOP marking identifies the installed button legend. However, the complete assembly has not been independently verified as a certified emergency-stop safety device. It should not be used as a safety-rated emergency shutdown control without confirmation of the required application, electrical ratings, and applicable safety standards.
• The installed cover, button lens, and wiring harness have not been assigned separate manufacturer part numbers because their exact individual configurations have not been verified.
• This assembly was removed from an uncommissioned equipment cabinet before the cabinet was placed into service. Individual switch operation and the complete wiring harness have not been independently functionally tested.
• Buyers should verify the switch's maintained-action operation, contact arrangement, mounting requirements, and conductor assignments before installation.
