The ABB CE4P‑10R‑01 is a compact emergency stop pushbutton designed for use in industrial control and safety systems. It features a red 40 mm mushroom head actuator with a pull‑release mechanism, allowing the operator to press the button to stop machinery or equipment in an emergency and then reset it by pulling the head back. This device is non‑illuminated and part of ABB’s 22 mm modular/compact pilot device range, suitable for control panels and machinery where quick emergency shutdown is required.
