SENSOR AND SENSOR WITH CONNECTING DEVICE

摘要

PROBLEM TO BE SOLVED: To constitute reasonably a sensor which can detect accurately whether a buckle and a tang are being locked or unlocked. SOLUTION: A sensor S is arranged with a latch material 40 which attains a connecting situation by engaging a tang, based on the connecting operation of the tang, and with a lock pin LP of magnetic nature which maintains the latch material in connecting situation. One tip of this lock pin LP is projected toward the outer direction further than the side wall of the lock structure L so that the sensor can detect whether the tang T is connected or not connected, judging by the movement of the projected tip.
