The 7201SY9AV2QE is a miniature DPDT toggle switch from the C&K 7000 Series, designed for compact electronic applications requiring reliable switching functionality. This switch features vertical right-angle PC through-hole termination with 0.150" pitch spacing, making it suitable for standard PCB mounting. The switch operates over a temperature range of -30°C to 85°C and provides contact resistance below 10 mO typical at 2-4 V DC with 100 mA, ensuring low-loss signal transmission. With an insulation resistance of 10? O minimum and dielectric strength of 1000 Vrms at sea level, this switch delivers robust electrical isolation and safety margins. The DPDT configuration with two independent switching poles enables versatile control applications in industrial equipment, consumer electronics, and instrumentation systems where space constraints and reliable switching performance are essential.
