LS-I Pull Cord Switch: Reliable Safety Solution for Industrial Applications
The LS-I Pull Cord Switch serves as a critical component in industrial safety systems, specifically engineered for emergency stop control of various machinery. Featuring a modular design with highly responsive activation mechanism, this product ensures immediate response to operational emergencies. The housing combines engineering-grade polymer and metal alloy composites, treated with anti-corrosion coating to maintain stable performance within -25℃ to +75℃ temperature range and ≤95% humidity environments.
With optimized mechanical transmission structure, this switch enables dual-direction activation capability, providing ±30° maximum allowable deflection angle for extended protection coverage. The core components incorporate gold-plated contacts with less than 0.03Ω contact resistance, ensuring over 100,000 operational cycles. The triple-sealed construction effectively prevents dust and moisture ingress, achieving IP65 protection rating for demanding applications in mining, construction material processing, and port logistics.
Multiple installation options including wall-mounting and bracket-fixing configurations adapt to different cable types (6-12mm diameter steel wire or nylon cord). Maintenance-friendly access panel allows tool-free routine inspection. Optional audible/visual alarm modules and status indicators are available for real-time system monitoring, meeting diverse industrial requirements.
