The invention relates to a micro-switch type automotive central door lock fastener and a production process thereof. The micro-switch type automotive central door lock fastener comprises a shaft snap spring, a fastener action output oscillating bar, a sealing ring, a reset torsion spring, a worm gear, a locking cushion, a fastener output shaft, a sector gear, an unlocking bumper block, a driving cam bit, a worm gear rotating shaft, a lower fastener shell, a motor electrode, a micro-switch binding post, a micro-switch, a motor, a pinion, a worm and an upper fastener shell. A signal extraction mechanism of the central door lock fastener utilizes the high-performance micro-switch to substitute for a reed and a slip sheet of a traditional fastener, and corresponding mechanisms of the fastener are appropriately designed and adjusted.
