ABSTRACT:
A buckle device with a switch for detecting tongue-lock comprises a base, a latch piece supported on the base so as to move between a tongue-lock position and a tongue-unlock position, a lock plate provided so as to move between an engaged position at which the latch piece remains stationary in the tongue-lock position and a disengaged position which permits movement from the tongue-lock position of the latchpiece, such that the lock plate moves to the engaged position following the movement of the latch piece to the tongue-lock position, a release button for setting the lock plate in the disengaged position; and a switch assembly for detecting whether the lock plate is located in the engaged position or not.
