Description

This Harmony XB4, black head with key (key no.455) for key selector switch has 2 positions, operates with spring-return-from-right-to-left mechanism with key withdrawal on left position. This head with key provides a versatile interface for controlling your machines. It is easily installed and replaced on compatible complete key selector switch units to provide 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. It has a metal bezel, this makes it Ideal for applications requiring high impact and vibration resistance. It is designed to fit in a standard 22mm cutout, ensuring compatibility when installing in pre-existing machinery. Secure machine and system operation with a key, only available to authorized operators. Its wide range of operating temperatures from -40°C to 70°C allows versatility in usage of product. Key removal allowed in only one of the positions, allowing for advanced interlocking between various parts of a machine or process, while limiting human errors.

Features

This 22mm metal head features a specialized key-actuated mechanism that locks the control switch in place, ensuring only authorized key-holders can toggle your system between states. It is the gold standard for industrial security, preventing accidental startups or tampering in high-stakes manufacturing and commercial environments.
The internal cylinder is specifically configured to allow key removal only in the left (rest) position. This provides a physical layer of security for your control panel, allowing supervisors or authorized personnel to disable the machine and take the key with them, effectively preventing unauthorized operation or tampering by untrained staff during off-shifts.
Built with Schneider s legendary XB4 metal construction, this operator features a heavy-duty chromium-plated metal bezel that resists corrosion, chemical exposure, and mechanical impact. Unlike plastic alternatives, this rugged design maintains its structural integrity and premium feel in high-vibration environments, making it the industry standard for automotive, oil and gas, and heavy industrial automation panels
This key switch is fully sealed to meet IP66, IP67, and IP69K standards, providing total protection against dust ingress and high-pressure water jets. Whether your facility requires daily sanitization or the panel is exposed to the elements, the ZB4BG6 ensures continuous electrical conductivity and mechanical reliability, significantly reducing the risk of circuit failure due to moisture or contaminants.
As part of the modular Harmony XB4 range, this head unit easily snaps onto a standard mounting collar and can be paired with any combination of NO (Normally Open) or NC (Normally Closed) contact blocks. This flexibility allows industrial engineers to tailor the electrical output to their specific logic requirements whether controlling a simple relay or sending a pulse to a PLC without needing specialized tools for installation.
