The T203S1CFABE is a subminiature toggle switch from C&K Components featuring a double-pole double-throw (DPDT) configuration with three positions: ON, OFF, and ON. It is designed with right-angle PC thru-hole termination and horizontal actuation, providing a compact footprint suitable for space-constrained applications. 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. With an insulation resistance of 10? O minimum and dielectric strength of 1000 Vrms at sea level, this switch delivers reliable electrical performance. The device is ideal for hand-held telecommunications, instrumentation, and medical equipment applications where compact size and reliable switching are essential.
