A10305RNZQK is a single-pole rotary switch from the A Series designed for multi-position switching applications. Based on the A Series specifications, this switch features positive detent operation with 5-position capability and supports both shorting and non-shorting contact configurations. The switch is rated for 2.5 AMPS @ 125 V AC and 350 mA @ 125 V DC (UL/CSA), with a continuous carry rating of 5 AMPS, and achieves contact resistance below 20 mO typical at 2-4 V DC with 100 mA. It offers an electrical life of 15,000 make-and-break cycles at full load and up to 300,000 detent operations, with insulation resistance of 10? O minimum and dielectric strength of 1,000 Vrms minimum at sea level. The switch operates reliably across -30°C to 85°C and is RoHS compliant, making it suitable for automotive, appliance, and industrial equipment applications.
