The ABB CE4K1‑10R‑11 is a compact emergency stop pushbutton designed for industrial control panels, machinery interfaces, and safety circuits. It features a red mushroom‑style actuator with a key release mechanism, allowing the button to be reset only with a key after it is pressed. This prevents accidental resetting and enhances safety. The device is part of ABB’s Compact pilot‑device range and is suitable for environments that require durable, clear emergency stop control.
