YT1063520FPLFS is a right-angle sealed tactile switch from the KT Series designed for surface mount technology (SMT) applications. It features a single-pole, normally-open (SPST, N.O.) contact arrangement with gullwing-type terminals optimized for SMT assembly, and provides IP57 protection against dust and moisture ingress. The switch is rated for 1.0 VA maximum at 32 V AC or DC, with contact resistance below 50 mO typical and an electrical/mechanical life of 100,000 make-and-break cycles at full load. Operating temperature range spans -40°C to 90°C, with dielectric strength of 250 Vrms minimum at sea level and insulation resistance of 10? O minimum. This switch is ideal for telecommunications, computer products, instrumentation, and power supply applications where reliable sealed switching and high shear force with an extended bracket are required.
