Schneider Electric Harmony XB4 Series Key Switch Head, 90° Angle of Throw, 22mm Cutout Diameter - ZB4BG612


This key switch head provides a secure, panel-mounted operator for control systems, offering two selectable positions and a spring-return mechanism that centres the actuator after use. It is designed for industrial environments where keyed access, Compact 22mm panel cut-outs, and robust protection against water and contaminants are required.

Features & Benefits


• IP66 IP67 IP69 protection keeps internals operational in wet conditions
• 90° mechanical travel enables clear two-position selection
• Spring return to centre reduces false latching and operator error
• 1,000,000 cycle mechanical life minimises maintenance interventions
• Chromium-plated metal bezel provides enhanced surface durability
• Key 421E compatibility enforces controlled access to circuits

Applications


• Suitable for control panels requiring restricted operator access
• Ideal for machinery safety interlocks with keyed operation
• used with automation cabinets exposed to washdown cleaning
• Can be used for marine and offshore switch panels needing high ingress protection

How is the key removed and how does that affect panel security?


The key withdraws in the left position only, ensuring the actuator can be locked out at a defined orientation for secure access control.

What mechanical stresses can the head tolerate during operation?


The unit withstands vibration up to 5gn (2 to 500 Hz) and shock pulses of up to 50gn, suitable for demanding industrial conditions.

How does the product resist high-pressure cleaning?


It is rated to resist high-pressure washer exposure at 7,000,000 Pa and 55°C from 0.1 m, supporting hygiene cleaning regimes.

What mounting considerations apply for panel installation?


It fits a 22mm cut-out and presents a round Compact head profile for front mounting using single or combined contact blocks.
