Overview
The Schlegel Elektrokontakt BZOI is a precision-engineered twin-contact momentary switch designed for industrial control systems requiring reliable, low-maintenance switching. This switch features a 3mm travel distance with a snap-action mechanism, ensuring consistent actuation and long operational life. The contacts are made from AgNi (silver-nickel) alloy, providing excellent conductivity and resistance to wear, oxidation, and arcing—critical for high-cycle applications. The Faston terminals (2.8 x 0.8 mm) enable secure, vibration-resistant connections, compatible with standard crimp-on terminals and quick-connect systems. Electrical performance is rated to IEC/EN 60947-5-1 and IEC/EN 61058-1 standards, with a rated insulation voltage of 250V AC/DC and a thermal continuous current of 6A. The BZOI supports use cases from 1mA/5V minimum switching to 1.5A at 240V AC or 0.2A at 250V DC, with a mechanical and electrical life of 1 million switching cycles at rated load. Prell time is under 10ms for both NO and NC contacts, ensuring fast response in control circuits. The switch includes one normally closed (NC) and one normally open (NO) contact, offering flexibility for control logic configurations. It is rated IP00 for basic protection, making it suitable for use in control panels, machinery safety circuits, and automation systems where reliable, frequent operation is required. The BZOI is part of Schlegel Elektrokontakt’s industrial switching portfolio, a manufacturer known for precision components in automation and control applications.
