Overview

The Schlegel Elektrokontakt BZLOI5K is a precision-engineered momentary switch designed for industrial control systems requiring reliable actuation and visibility. This switch features a 3 mm travel distance for precise operation, making it ideal for applications where exact switch actuation is critical. The contact configuration includes 1 Normally Closed (NC) and 1 Normally Open (NO) contact, both constructed from AgNi (silver-nickel) for superior conductivity and durability under repeated cycling. The screw connection type ensures secure cable retention, supporting wire cross-sections up to 2.5 mm² and accommodating AWG 26-14, which simplifies installation and reduces maintenance time. The integrated T55K lamp holder provides illumination at 24V AC/DC with an operating current of 11 mA, enhancing visibility in low-light environments or control panels. Rated for Protection Class II with protective insulation, the BZLOI5K meets EN 60947-5-1 standards for positive opening contacts, ensuring safety and compliance in industrial applications. With a rated insulation voltage of 300V (600V for related models), thermal continuous current of 16A, and a lifetime of 1 million switching cycles at rated load, this switch delivers long-term reliability. It supports AC15 operation at 240V/3A and DC13 operation at 250V/0.2A or 24V/2A, making it versatile for both AC and DC control circuits. The BZLOI5K is manufactured in Germany by Schlegel Elektrokontakt, a leader in industrial switching solutions, and is distributed by Gross Automation for North American markets. Typical applications include machinery control panels, automation systems, emergency stop circuits, and industrial safety systems where dependable switching and clear indication are required.
