Overview
The Schlegel Elektrokontakt BZII (SKU: BZII) is a robust momentary switch designed for precise industrial control applications. This switch features a momentary action with a 3 mm travel, ensuring reliable actuation. It is equipped with 2 Normally Open (NO) contacts, constructed from durable AgNi (Silver-Nickel) material, known for its excellent conductivity and resistance to wear, contributing to a long operational life of 1 million switching cycles at rated load. The connection method utilizes Faston terminals (2.8 x 0.8 mm), facilitating secure and efficient wiring in control panels and machinery. Adhering to protection class II (protective insulation), the BZII switch offers enhanced electrical safety. It meets stringent standards including EN 60947-5-1 and EN 61058-1. Technical specifications include a rated insulation voltage (Ui) of 300V, a thermal continuous current (Ith) of 16A, and rated operating current (Ie) of 3A at AC15 (240V) and 0.2A at DC13 (250V). The switch is manufactured in Germany, reflecting a commitment to quality and precision engineering. Ideal for integration into automation systems, machine controls, and electrical enclosures where dependable momentary switching is critical. The absence of labeling options on this model simplifies its application in standardized control layouts.
