Yueqing Huilong’s spring limit switch stands out for its innovative mechanical design, combining a high - tensile stainless - steel spring with a precision - cast plastic actuator. The spring mechanism, calibrated to withstand 500N of force, ensures consistent triggering at pre - set positions, while the self - resetting feature eliminates manual adjustment. The switch housing is made from flame - retardant ABS plastic (UL94 V - 0 rated), suitable for operating temperatures from - 25℃ to + 80℃. Its gold - plated contacts offer low contact resistance (≤50mΩ), reducing arcing and improving switching reliability. Commonly used in elevator door systems, packaging machines, and material handling equipment, this switch supports both normally open (NO) and normally closed (NC) configurations. The spring limit switch also features a modular mounting system, allowing 360° adjustment for optimal alignment with moving parts, minimizing installation time by 40% compared to traditional models.
