A20305RNZQ is a rotary switch from the A Series designed for multi-position switching applications requiring reliable contact operation. The switch features positive detent positioning with electrical ratings of 2.5 AMPS @ 125 V AC and 350 mA @ 125 V DC (UL/CSA), supporting continuous carry current of 5 AMPS. It offers contact resistance below 20 mO typical at 2-4 V DC with 100 mA, insulation resistance of 10? O minimum, and dielectric strength of 1,000 Vrms minimum at sea level. The switch operates reliably over a temperature range of -30°C to 85°C with electrical life rated at 15,000 make-and-break cycles at full load and up to 300,000 detent operations. This switch is ideal for automotive, appliance, and industrial equipment applications where durable, multi-position switching with positive detent is required.
