The SparkFun Rotary Switch Potentiometer Breakout is a small board the allows you to add resistors to a 10-position rotary switch, turning it into a potentiometer with 10 discrete steps. Multiple applications require potentiometers that are hard to find due to specific resistance values or custom tapers, the Rotary Switch Potentiometer board allows you to populate your own resistors to help match situations where ordinary parts aren’t available or suitable. Specific resistors can also be used in situations where you want distinct steps or selections, such as being able to consistently select to a value.
Each Rotary Switch Potentiometer Breakout provides you with nine spots on the board for resistors (positions 1 through 9). These resistors are bent like a hair pin, and soldered in place “standing up.” On the opposite side of the breakout you will find three pins to attach leads or a connector which include, CCW (Counterclockwise end of resistor string), W (Wiper), and CW (Clockwise end of resistor string).
Note: A 10-position rotary switch is NOT included with this breakout. Check the Recommended Products section below for the correct switch.

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
