The T201KV3QE is a subminiature double-pole toggle switch designed for compact, space-constrained applications requiring reliable switching functionality. This switch features a vertical actuation design with V3 vertical mount V-bracket configuration and PC-mount termination, providing flexible installation options for both panel and PC board mounting. The switch operates over a temperature range of -30°C to +85°C and offers contact resistance below 20 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, it delivers robust electrical isolation and safety margins. The T201KV3QE is commonly used in hand-held telecommunications equipment, instrumentation, and medical devices where compact size, reliability, and precise switching control are essential.
