Description

Harmony 22 mm modular push buttons, selector switches, pilot lights are designed for industry. This range combines simplicity of setup, flexibility and a robust construction. An ingenious locking system consisting of a snap fit head and body that can be tightened with a single screw but still ensuring an easy and yet secure mounting. Harmony XB4/ZB4 are 22 mm chromium plated metal modular push buttons, selector switches and pilot lights connecting to fully metal mounting collar. The operators can be purchased as complete operators or various modules that can be assembled to meet the user’s specific requirement. Harmony XB5/ZB5 are 22 mm plastic modular push buttons, selector switches, pilot lights. The operator can have a round and square plastic bezel. It has a metal bezel, this makes it Ideal for applications requiring high impact and vibration resistance. The contacts can be used for low load electrical contact and high power applications. Shake proof connection screws make periodic retightening unnecessary. A complete set of accessories to provide a solution for applications where exposure to high pressure cleaning, dust and extreme temperatures is an everyday occurrence. These harmony 22mm push buttons are used by machine manufacturers (automotive, textiles, timber) and control system panel builders. Certified and approved for meeting requirements throughout all continents: EN/IEC, UL, NEMA, CSA, CCC, Gost, JIS and many more. They have UL and CE markings and have ratings up to IP66 and IP69K.

Features

Designed for universal 22mm mounting cutouts, this robust chromium-plated metal head integrates seamlessly into standard machinery interfaces, push-button enclosures, and motor control centers. The standardized Schneider Electric Harmony XB4 footprint saves panel builders significant installation time while providing a highly durable, rigid mounting solution that strictly prevents spinning or loosening during heavy operator use.
Engineered for the harshest manufacturing environments, this push-button head is fully sealed against extreme dust, moisture, and high-temperature water jets. This unparalleled IP66, IP67, and IP69K ingress protection makes it the perfect, reliable solution for food and beverage processing facilities or outdoor applications, completely eliminating the risk of internal water damage and costly control system short circuits.
Featuring a flush, spring-return (momentary) green lens designed for use with integral LED contact bodies, this actuator provides highly visible, immediate visual feedback for critical "Start" or "Power On" commands. The vibrant illumination paired with a snag-free flush profile ensures operators can confidently trigger production processes in low-light industrial settings while actively preventing dangerous accidental actuations from passing equipment or personnel.
Rated for an incredible 10 million mechanical operating cycles, this industrial-grade push-button actuator is built to survive constant, repetitive actuation on busy, high-volume factory floors. Fully certified to rigorous UL, CSA, and CE standards, relying on this premium component guarantees your automated machinery meets strict global safety codes and drastically reduces long-term maintenance downtime and replacement costs.
