This is the SparkFun Rotary Switch Breakout, a very simple board designed to easily provide you access to each pin on our 10-position rotary switches. This breakout allows you to easily add a rotary switch to your next project without having to worry about attaching its unique footprint to a custom board or solderless breadboard. All you need to do is solder the 10-position rotary switch into the breakout (using the silkscreen on the board as a guide) and each pin will become available for breadboard or hookup wire compatibility.
Each one of these boards breaks out the common ( C ), 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10 positions on the board into 0.1" spaced pins.
Note: A 10-position rotary switch is NOT included with this breakout. Check the Recommended Products section below for the correct switch.
