22 mm emergency stop push buttons

22 mm is the most common panel hole for emergency stop buttons on industrial machinery. Jinhong makes four plastic 22 mm series, all with IP65 front protection and push-lock turn-reset action. They differ mainly in rating, head range and terminal style.

An emergency stop button is a component. Whether the complete stop function meets EN ISO 13850 and the machine's risk assessment depends on how it is wired and evaluated, which is the machine builder's responsibility. Our emergency stop button guide explains latching, reset and wiring in more detail.
