Flat white push button with self-resetting function, unmarked Harmony XB7 XB7NA11

Control button – reliability and simplicity in every detail

This flat, momentary button with a diameter of 22.5 mm is part of the Harmony XB7 series from Schneider Electric, designed for demanding industrial applications. Made in white with a black front ring, it is a discreet yet functional element of the control panel. Its construction based on screw connections ensures a solid and durable electrical connection.

Construction and application

The button is designed for mounting in 22.5 mm diameter holes and offers a single control position with one normally closed (NC) contact. The momentary mechanism ensures immediate reset after release, which is crucial in applications requiring fast response. The lack of backlighting and markings on the front of the button makes it ideal for situations where minimalism and versatility are a priority. This allows it to be easily adapted to different control schemes and labeled according to the needs of a specific application.

Durability and protection

The button is designed to operate in harsh industrial conditions. The IP54 protection rating guarantees resistance to dust and splashing water, making it an ideal solution for environments with an increased risk of failure due to contamination. Additionally, it meets NEMA 12 standards, confirming its reliability under specific operating conditions. The material of the front ring made of plastic ensures mechanical durability and corrosion resistance.
