Brake light switch with two conductors, correct for most "Series" models. This switch is also commonly used with most updated modern "conversion" harnesses and systems. When this switch is mounted it employs "normal-open" operation, meaning the switch does NOT make contact in the normal resting position and then makes contact when the pedal is activated and releases the cam.
