This Schneider Electric Harmony XB4 modular black push-button operates with a spring return / impulse mechanism and uses screw clamp terminals. It has 1 x NO contact and a chromium-plated metal bezel with a clear silicone boot. This push-button provides a simple and robust control to machines and processes. It is easily installed into standard 22 mm diameter cut-outs and connected with simple screw-clamp connections. Its schematic is clearly distinguishable thanks to clear colors and markings, minimizing errors during initial wiring and later maintenance operations. It is impact resistant, dust proof, waterproof and vibration resistant thanks to its IP66 / IP67 / IP69 / IP69K, making it ideal for operation in harsh environments.
