The 7203MD9V3BE is a miniature toggle switch from the C&K 7000 Series designed for vertical mounting with a V-bracket configuration. This SPDT (Single Pole Double Throw) switch features an epoxy seal and is optimized for PC board mounting with a 0.073 inch diameter mounting hole. The switch operates over a temperature range of -30°C to 85°C and offers contact resistance below 10 mO typical at 2-4 V DC with 100 mA. With an insulation resistance of 10? O minimum and dielectric strength of 1000 Vrms at sea level, this switch provides reliable electrical isolation and performance. The device is commonly used in industrial control panels, consumer electronics, and instrumentation applications where compact, reliable switching is required.
