The Lorlin IRL Series is a specialised range of keylock switches distinguished by their "impulsion" or spring-return functionality, making them an ideal solution for momentary signal applications. Manufactured in the UK, these switches are designed for a standard 16mm panel cut-out and are particularly suited for reset functions, motor starters, and security override controls where a temporary electrical connection is required. The series features a robust zinc alloy housing with the option of a parallel or tapered bezel, providing both mechanical durability and a professional finish for modern equipment panels. Engineered for reliable performance in demanding environments, the IRL Series utilizes a 5-disc lock mechanism that supports both common key (keyed-alike) and random key (keyed-differ) configurations. The switches offer a 60-degree indexing angle and are available in double-pole configurations, providing versatile circuit control within a compact frame. To ensure ease of use, the series includes double-entry keys that can be inserted in either orientation and is designed with a rear projection of less than 30mm to accommodate shallow enclosures and densely populated control systems. The IRL Series is built to high technical standards, featuring silver-plated brass contacts as standard with an electrical rating of 1A at 24V DC or 115V AC. The switch mouldings are constructed from high-quality glass-filled polyamide 6.6, achieving a UL94V-0 flammability rating for enhanced safety. Capable of operating in temperatures ranging from -20°C to +65°C and tested to a mechanical life of 10,000 cycles, the IRL Series provides a dependable and secure momentary interface for industrial, security, and commercial electronics.
