Limit Travel Switch with 2 Wires

The FSK-14 features a dual waterproof and dustproof design with 'structural sealing and material protection,' fully compliant with the IP67 international protection standard (IEC 60529), achieving complete dustproofing and the ability to withstand immersion in 1 meter of water for 30 minutes without leakage. Its sealing structure uses a patented reinforced design: highly elastic fluororubber seals are embedded at the casing seams and combined with ultrasonic welding for seamless junctions. The cable interface at the rear uses a crimped sealing sleeve, forming a fully enclosed protective barrier that completely blocks the entry of moisture, dust, oil, and other contaminants, making it suitable for complex environments such as workshop spraying, outdoor rain and snow, and coastal salt fog.

Equipped with a medium-to-heavy duty rapid-action trigger mechanism, it uses thickened beryllium copper springs and a reinforced contact base. The actuation travel can be customized between 0.6-1.5mm, and the operating force ranges from 1-5N, balancing the convenience of manual operation with the stability of mechanical triggering. The press provides clear and strong feedback, with no sticking or lag. The mechanical lifespan exceeds 100,000 cycles, and the electrical lifespan reaches 10,000 cycles. Based on a daily operation frequency of 20 times, it can be reliably used for over 2 years.
