The A12405RNZQ is a single-pole rotary switch from C&K Components designed for multi-position switching applications in automotive, appliance, and industrial equipment. This model features 4-position detent operation with 30° indexing, non-shorting (break-before-make) contacts, and solder lug termination for reliable connection. The switch is rated for 2.5 A at 125 V AC or 350 mA at 125 V DC, with a continuous carry rating of 5 A and contact resistance below 20 mO typical. It delivers 15,000 make-and-break cycles at full load with up to 300,000 detent operations, 1,000 Vrms dielectric strength, and 10? O minimum insulation resistance. Operating across -30°C to +85°C, the switch is panel-mounted with a 3/8-32 threaded stud and includes RoHS-compliant construction, making it suitable for demanding switching applications requiring positive detent positioning and long electrical life.
