This Harmony XB5, flush modular black push button operates with a spring return / impulse mechanism and uses screw-clamp terminals. This push button provides a simple and robust control to machines and processes. It is easily installed into standard 22mm diameter panel cut-outs and connected to control circuits with classic screw-clamp connections. Its schematic is clearly distinguishable thanks to clear colors, minimizing errors during initial wiring and later maintenance operations. It is impact resistant, dust resistant, water resistant and vibration resistant thanks to its IP66, making it ideal for operation in harsh environments. Its plastic bezel makes it ideal for applications requiring good resistance to chemical agents and/or double electrical insulation.
