LL-A Series Emergency Pull Cord Switch
The LL-A series emergency pull cord switch is engineered for industrial equipment emergency shutdown and safety control systems. Featuring modular architecture and precision manufacturing, it balances operational sensitivity with mechanical durability. The housing combines high-strength engineering plastics with metal protective components, providing effective resistance against dust, oil contamination and mild chemical corrosion. Bidirectional activation mechanism enables simultaneous control from both sides of equipment, with self-locking function ensuring immediate response during emergencies.
Equipped with impact-resistant isolation structure, the internal components are protected from external forces. Spring reset system guarantees automatic position recovery. Ideal for mining machinery, port conveying systems and automated production lines, demonstrating exceptional performance in long-distance conveyor applications. Simplified installation process through optimized wiring design supports horizontal/vertical multi-angle mounting, complying with industrial ergonomic requirements.
LX-52 Series Compact Pull Cord Switch
The LX-52 series adopts space-saving integrated design delivering reliable emergency braking functionality in confined spaces. Enhanced sealing structure with precision injection molding achieves IP65 protection level, suitable for high-humidity environments and outdoor applications. Innovative dual-contact protection mechanism significantly reduces accidental activation risks, complemented by visual operation indicator for status monitoring.
Particularly recommended for food processing, packaging machinery and logistics systems requiring strict hygiene standards. Smooth surface treatment facilitates easy cleaning and maintenance. Low-power circuit design with universal interfaces ensures compatibility with multiple control systems. Built-in damping mechanism effectively absorbs mechanical vibration impacts. Customizable options include variable cord lengths (1.5-10m selectable) and color-coding solutions for personalized configuration.
