Schneider Electric ZB5AA335 Push Button Head, Black, Spring Return

The Schneider Electric ZB5AA335 is a high-quality flush push button head designed for industrial control applications. Featuring a sleek black finish and an intuitive "up arrow" marking, this component is engineered for seamless integration into the Harmony XB5 and XALF series control stations. Its robust plastic construction ensures durability in demanding environments, while the spring return mechanism provides reliable, tactile feedback for machine operation and signaling.

Advantages

This push button head offers exceptional reliability due to its high-grade plastic housing, which is resistant to common industrial wear and tear. The spring return functionality ensures that the button automatically resets after each press, preventing accidental activation and maintaining consistent control sequences. Its compact design allows for efficient space utilization within control panels, and the standardized 22 mm mounting diameter ensures compatibility with a wide range of existing electrical automation systems.

Suitable for

• Industrial machine control panels
• Electrical automation systems
• Signaling and human-machine interface applications
• Control stations requiring directional input

This component may not be suitable for environments requiring heavy-duty metal enclosures or specific ingress protection ratings beyond the standard specifications of the Harmony XB5 series. It is also not intended for applications requiring a maintained or latching switch action, as the spring return mechanism is strictly designed for momentary operation.

Key specifications

• Color: Black
• Marking: Up arrow
• Material: Plastic
• Mounting diameter: 22 mm
• Mechanism: Spring return
• Dimensions: 29 mm x 29 mm x 28 mm
• Compatibility: Harmony XB5 and XALF series

To install the ZB5AA335, ensure the control panel is de-energized to maintain safety. Insert the push button head into a standard 22 mm hole on the panel front and secure it using the appropriate locking nut from the rear. Once the head is firmly in place, attach the corresponding contact block to the back of the actuator. Verify that the spring return mechanism operates smoothly before reconnecting power to the system.

What to consider before purchase

• Ensure the 22 mm mounting hole size matches your panel configuration.
• Verify that the momentary spring return action meets your specific control requirements.
• Confirm compatibility with your existing Harmony XB5 or XALF contact blocks.

For optimal performance and longevity, ensure the push button is kept free of excessive dust or debris that could impede the spring return mechanism. Regular inspection of the mounting hardware is recommended to maintain a secure fit in high-vibration environments.
