The HW-CBF11 is a standard fingersafe contact assembly designed for use with IDEC's 22mm IEC-style non-illuminated pushbuttons and emergency stop switches. This contact block provides a 1NO-1NC (one normally open, one normally closed) configuration with IP20 finger-safe protection as standard. The assembly features slow make double break self-cleaning contacts and is part of the modular HW Series platform, allowing it to be combined with various mounting adapters, safety lever locks, anti-rotation rings, and operators to create complete switch units. The HW-CBF11 is widely used in industrial control applications, machinery safety systems, and emergency stop circuits where reliable contact switching and operator protection are essential requirements.
