A10303RNCQ is a three-pole rotary switch featuring 3-position operation with 30° indexing and positive detent action. The switch utilizes silver-plated coin silver movable contacts and brass stationary contacts with silver plating, delivering contact resistance below 20 mO typical at 2-4 V DC with 100 mA. It is rated for 2.5 AMPS @ 125 V AC and 350 mA @ 125 V DC (UL/CSA), with continuous carry capacity of 5 AMPS and electrical life of 15,000 make-and-break cycles at full load. The housing and actuator are constructed from glass-filled 6/6 nylon (UL 94V-0), with operating temperature range of -30°C to 85°C and insulation resistance of 10? O minimum. This switch is ideal for automotive, appliance, and industrial equipment applications requiring reliable multi-pole switching with positive positioning.
