One push of the actuator instantly releases normally closed contacts, thus immediately terminating power. The switches are re-activated either by hand twisting the actuator, or when additional security is required, by unlocking the actuator with a key. They satisfy international standards including the new DIN EN ISO 13850, which replaced the EN 418 directive from 1st March 2007, that demands a “foolproof” switch operation.

Built for strength, they will even endure a heavy frontal impact that is often the case in a panic situation.

EAO offers the heavy-duty Series 04 and Series 44 Emergency-stop for large machinery applications, a 37mm diameter switch for 22.5mm mounting. For space restricted applications, such as compact test equipment, EAO manufacturers the Series 61, a 27mm diameter switch for mounting in a 16 mm cutout.

If poor lighting conditions are an issue, EAO offers a compact, illuminated ‘foolproof’ mono-block design Series 84 Emergency-stop switch, which also benefits from side-visible illumination and a short back-panel depth.
