{"title":"Dual-Gang 20K Potentiometer with Rotary Switch","handle":"dual-ganged-potentiometer-with-rotary-switch","url":"/products/dual-ganged-potentiometer-with-rotary-switch","description":"This adjustable dual-gang potentiometer gives you two linked variable resistors on a single shaft, making it handy for interfaces where two channels need to move together. Turn the shaft and the resistance changes, so it can be used to create a variable voltage for an analogue input.Connect VCC to one outer pin, GND to the other, and the centre pin will provide a voltage that varies from 0 to VCC depending on the rotation. Feed that centre pin into an ADC on a microcontroller to read a user-adjustable control.Dual-gang potentiometers are commonly used for stereo audio volume control and similar applications where matched adjustment across two channels is required. This part also includes a built-in rotary SPST switch, with PC pin termination, board locks and panel-mount hardware style.Specifications:Resistance (Ohms): 20KTolerance: ±20%Power (Watts): 0.025W, 1/40WBuilt in Switch: Rotary, SPSTNumber of Turns: 1.0Taper: LogarithmicNumber of Gangs: 2Adjustment Type: Side AdjustmentRotation: 300°Resistive Material: CarbonTermination Style: PC Pins, Board LocksActuator Type: FlattedActuator Length: 15mm (0.591\")Actuator Diameter: 6mm (0.236\")Bushing Thread: M7 x 0.75Mounting Type: Panel Mount","vendor":"SparkFun","product_type":"Potentiometer","in_stock":true,"options":[],"variants":[{"id":16100,"title":"Default Title","sku":"SF-COM-29199","mpn":"COM-29199","price":13.65,"on_sale":false,"in_stock":true,"available_quantity":278}]}
