It weighs 0.188 kg (0.414 lb) and offers an operating travel of 0.06 in (1.5 mm) for NC state changes, a total travel of 0.2 in (4.3 mm), and an operating force of 44 N, with a mechanical durability of 300,000 cycles; the button is a red unmarked mushroom head with key release and slow‑break operation. As a complete control station in the Harmony XALK family, it is designed for emergency‑stop applications and can be configured with up to three NO or NC contact blocks per operating head to tailor the panel to specific safety and control needs.
