The 7201P3D9V71RE22 is a miniature toggle switch from the C&K 7000 Series designed for compact electronic applications requiring reliable switching control. This DPDT (Double Pole Double Throw) switch features a vertical mount V-bracket termination with epoxy seal protection, suitable for PC board through-hole mounting with 0.150" pitch spacing. The switch operates over a temperature range of -30°C to 85°C and maintains contact resistance below 10 mO typical at 2-4 V DC with 100 mA, ensuring consistent electrical performance. With an insulation resistance of 10? O minimum and dielectric strength of 1000 Vrms at sea level, this switch provides robust isolation and safety margins. The device is ideal for industrial control panels, consumer electronics, and instrumentation applications where space constraints and reliable switching are critical requirements.
