Game Controller Triggers (left/right pair)
Cost: $2.95 each
Description: These triggers are the same ones found in modern game controllers. They have a 10k potentiometer that gets adjusted by the spring-loaded trigger. It ranges from about 2k - 9k ohm. You get all the pieces for a left and right pair. Keep in mind when putting these together that they are mirror images.
Note: There is now a breakout board available for these.
