A10403RNZQ is a 4-pole rotary switch designed for multi-position switching applications with 3-position detent and 30° indexing. The switch features positive detent operation with non-shorting contacts and is constructed with glass-filled 6/6 nylon (UL 94V-0) housing and actuator for durability. Contact materials include coin silver with silver plating on movable contacts and brass with silver plating on stationary contacts, delivering contact resistance below 20 mO typical and supporting 2.5 AMPS @ 125 V AC or 350 mA @ 125 V DC switching capacity with 5 AMPS continuous carry rating. The switch operates reliably over -30°C to 85°C temperature range with electrical life rated at 15,000 make-and-break cycles at full load and up to 300,000 detent operations. This rotary switch is ideal for automotive, appliance, and industrial equipment applications requiring robust multi-pole switching with positive positioning.
