Description

This Harmony XB4 modular black key selector switch (key no.455) has 2 positions, operates with a stay-put mechanism with key withdrawal on the left position. It has a metal bezel. This key selector switch provides a versatile interface for controlling your machines. It is easily installed into standard 22mm diameter cut-outs and connected to your control circuits with simple screw-clamp connections. It provides a secure manner for authorized staff to switch between process or machine operating modes. It is impact resistant, dust resistant, water resistant and vibration resistant thanks to its IP66 / IP67 / IP69 / IP69K, making it ideal for operation in harsh environments.

Features

Built with the rugged Schneider Electric Harmony XB4 heavy-duty metal construction, this 22mm selector switch easily withstands high-impact industrial operations, mechanical shock, and extreme vibration. By eliminating the frequent replacement costs associated with brittle plastic alternatives, it guarantees long-lasting, reliable performance across your high-traffic motor control centers and factory floor machinery.
Engineered as a 2-position, maintained key selector switch, this unit requires a standard Ronis 455 key to operate, with safe key withdrawal exclusively in the left-hand position. This provides a critical layer of physical lockout security for dangerous automated equipment, strictly limiting overrides to qualified maintenance personnel and actively preventing accidental or unauthorized startups.
Boasting exceptional IP66, IP67, and IP69K ingress protection, this completely sealed unit is impenetrable to heavy industrial dust, temporary water submersion, and high-temperature, high-pressure cleaning jets. This makes it an uncompromising, fail-safe control component for strict hygiene environments like food and beverage processing facilities, wastewater treatment plants, and heavily exposed outdoor enclosures.
This complete assembly includes a pre-installed, slow-break 1 Normally Open (NO) contact block featuring secure screw-clamp terminals that ensure vibration-proof wire retention. Its modular, snap-fit architecture is designed to drop universally into standard 22mm panel cutouts, saving panel builders and electricians valuable labor time during initial machine integration or emergency breakdown retrofits.
