A10505RNCQE is a single-pole, 5-position rotary switch from the A Series designed for multi-position switching applications. The switch features positive detent operation with 5 selectable positions and offers both panel and PCB mounting options. It 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. The switch provides 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. Operating temperature range is -30°C to 85°C, and the switch is RoHS compliant. This rotary switch is commonly used in automotive, appliance, and industrial equipment applications where reliable multi-position selection is required.
