Overview
The Schlegel Elektrokontakt BZOOK is a precision-engineered momentary switch designed for industrial control panels, machinery, and automation systems. This high-reliability switch features two normally closed (NC) contacts with AgNi (Silver-Nickel) contact material, ensuring superior electrical conductivity and resistance to arcing in demanding environments. The 2.5 mm screw connection terminals provide secure cable retention for wire cross-sections up to 2.5 mm², supporting thermal continuous current of 16 A and rated operating voltages up to 480 V AC/DC. With a rated insulation voltage of 600 V and a mechanical travel of 3 mm, the BZOOK delivers consistent switching performance over 1 million cycles under rated load. Compliance with EN 60947-5-1 and Protection Class II (protective insulation) enhances operational safety in industrial settings. Ideal for applications requiring momentary actuation such as emergency-stop reset buttons, control panel interfaces, and automated machinery, the BZOOK switch combines German engineering with robust construction for long-term durability. Its modular design integrates seamlessly with Schlegel’s contact block systems, offering flexibility for system expansion or retrofitting. Manufactured in Germany by Georg Schlegel GmbH & Co. KG, the BZOOK switch is a dependable choice for engineers and system integrators prioritizing reliability and precision in critical control circuits.
