The SS0503 Electronic Micro Switch is a precision-engineered mechanical actuation, and long-term durability. Developed to meet rigorous engineering standards, this micro switch combines a unique pulley/reset activation mechanism with robust electrical performance, making it an ideal choice for critical safety controls, automation systems, instrumentation, and electromechanical equipment.
Equipped with a patented pulley-activation design, this micro switch ensures smooth, consistent, and low-vibration actuation. The mechanism minimizes mechanical wear and provides a tactile reset function ideal for position sensing and repeated cycling applications.
Rated for 250V operation (data validated per IEC standards), the SS0503 delivers reliable contact performance across resistive and moderate inductive loads. Its silver alloy contact material ensures low contact resistance (<50mΩ) and minimizes arc erosion.
The switch is rated for >1 million electrical cycles (resistive load testing at 10A, 125VAC) due to its hardened stainless steel spring system and corrosion-resistant housing (IP67 rated upon sealed enclosure integration).
With compact dimensions (12.8 × 5.8 × 6.5 mm nominal), the SS0503 fits constraints in densely packed circuit boards or embedded devices without compromising performance.
Every SS0503 is subject to 100% functional testing at production stages to validate contact integrity, insulation resistance (>100MΩ at 500VDC), and actuation force consistency (0.5N ±0.1N).
