Overview
The Schlegel Elektrokontakt BZLII_AU is a precision-engineered momentary twin contact switch designed for industrial control systems requiring reliable, low-maintenance switching. This 2-pole Normally Open (NO) switch features AgNi gold-plated contacts for superior conductivity and corrosion resistance, ensuring consistent performance over 1 million switching cycles at rated load. The Faston terminal connection (2.8 x 0.8 mm) provides secure, vibration-resistant electrical connections compatible with standard 26-14 AWG wiring. Rated for 240V AC or 250V DC operation, the BZLII_AU delivers a thermal continuous current of 16A and meets EN 60947-5-1 standards for industrial control equipment. It operates at 240V AC (3A) or 250V DC (0.2A), with DC13 compatibility up to 24V (2A). The compact design integrates seamlessly into control panels, automation systems, and machinery requiring momentary actuation. Gold-plated AgNi contacts prevent oxidation while maintaining low contact resistance (<50 mOhm new), critical for signal integrity in control circuits. The switch features a 3mm actuation travel with a bounce time of <10ms, ensuring fast response in critical applications. With a mechanical and electrical life of 1 million operations at nominal load, this Class II insulated switch is built for long-term reliability. The BZLII_AU supports lamp illumination via W2x4.6d socket with a maximum lamp voltage of 60V and power of 1.2W, compatible with both LED and incandescent lighting. Operating temperature ranges from -30°C to 70°C (without illumination) or -30°C to 65°C (with LED illumination), with storage from -50°C to 85°C. Ideal for use in industrial control panels, machinery interfaces, automation systems, and safety circuits where momentary actuation and reliable contact performance are essential. The twin contact design with separate plungers enhances operational safety and redundancy in critical applications.
