2-position switch black with key 455 metal with return to center XB4BG21EX

Key switch for industrial applications

This robust key switch from the Harmony XB4 range is a reliable solution for controlling and protecting circuits in demanding industrial environments. Made of metal, it provides high resistance to mechanical damage and corrosion, making it an ideal choice for use in hazardous areas (IP65/IP67). A locking mechanism with a removable key in the left position further enhances safety, preventing accidental switching on or off of the device.

Design and application

The switch is designed for mounting in standard 22.5 mm diameter panel holes. It has one normally closed contact (1NC), which ensures reliable circuit switching. Thanks to the screw connection, installation is simple and quick, even for less experienced installers. The product finds wide application in the oil and gas industry, food industry, gas stations, and everywhere where high reliability and safety are required. It is certified by INERIS 04ATEX9004U, which confirms its compliance with ATEX standards for explosive atmospheres.
