Extended Product Information

FAQs

What is the primary function of the Eaton M22 Yellow Push Button Head?

Its primary function is as a maintained emergency stop switch. The yellow color and mushroom shape are designed for immediate visibility and quick operation to halt machinery.

Does this product include the electrical contact blocks?

No, this product is the push button head actuator only. Separate Eaton M22 Series contact blocks are required for the electrical switching functionality and must be purchased separately.

What does the 'maintained' function mean?

Maintained means that once the button is pressed, it will stay in that position (latched) until manually reset. It does not return to its original state automatically when released.

What kind of environments can this button withstand?

It is rated IP67/IP69K and NEMA 4X, making it suitable for harsh industrial environments, including those with dust, high-pressure water jets, and washdown procedures.

How is the button reset after an emergency stop?

The button typically requires a manual twist or pull to reset, depending on the specific contact block and mounting configuration used. Check the documentation for your specific setup.

Can this button be used for normal on/off operations?

While it performs electrical switching, it is specifically designed and recommended for emergency stop functions due to its maintained (latching) nature and highly visible actuator. Using it for regular on/off control is not its intended purpose and could lead to operational issues.

What is the size of the cutout required for installation?

A standard 22.5mm (approximately 7/8 inch) diameter cutout is required for mounting this button head.

Troubleshooting

Button is difficult to press or does not reset.

Check for obstructions around the button. Ensure the button head is correctly mounted to the contact block and that the contact block is properly installed in the panel. Clean the actuator surface.

Switch does not activate or deactivate the connected circuit.

Verify that the correct Eaton M22 contact blocks are attached and wired correctly. Check the wiring of the connected circuit and ensure the contact blocks are functioning properly. Consult the contact block's wiring diagram.

Poor sealing or water ingress.

Ensure the mounting gasket is properly seated and undamaged. Verify the button head is securely fastened to the panel and contact block. Inspect for any cracks or damage to the actuator body or lens.

Setup, Compatibility & Care

Setup:

  2. Mounting: Insert the button head into the cutout. If using with contact blocks, ensure the button head is properly secured to the module.
  3. Wiring: Connect the appropriate Eaton M22 contact blocks (sold separately) to the rear of the actuator according to the wiring diagrams provided with the contact blocks.

Compatibility:

  • This push button head is designed for use with Eaton M22 Series mounting adapters and contact blocks.
  • It is compatible with panels requiring a 22.5mm (standard 7/8 inch) diameter cutout.

Care:

  • Cleaning: Wipe the surface with a damp, soft cloth. Avoid using abrasive cleaners or solvents, which can damage the material and rating.
  • Inspection: Regularly inspect the button for any signs of damage, wear, or obstruction to ensure proper function. Check the seal for integrity, especially in washdown environments.
