Overview
The Schlegel Elektrokontakt LDTL is a precision-engineered momentary contact switch designed for industrial control panels, machinery, and automation systems. This high-reliability switch features a durable screw connection for secure wiring, a sleek charcoal bezel for a professional appearance, and a 6mm travel distance for tactile feedback. The 22.3mm panel cutout ensures compatibility with standard mounting configurations, while the illuminated design enhances operator visibility in low-light environments. The BA9s lamp holder supports standard lighting solutions, and the optional labeling feature enables clear identification for streamlined maintenance and operation.
Built to meet stringent industrial standards, the LDTL switch delivers consistent performance with an IP65/IP66/IP67/IP69K ingress protection rating, making it suitable for harsh environments. The rectangular form factor integrates seamlessly into control panels, and the 2mm front bezel height maintains a low-profile design. The switch operates reliably at up to 240V AC / 1.5A or 24V DC / 2A, ensuring compatibility with a wide range of control systems.
Ideal for applications requiring precise momentary actuation, the LDTL switch is widely used in industrial automation, machinery control, and safety systems. Its robust construction, compliance with IEC/EN 60947-5-1, and compatibility with standard lighting solutions make it a versatile choice for engineers and system integrators. The screw connection type ensures stable and long-lasting electrical contact, reducing the risk of intermittent failures in critical applications.
