Abstract
A seat belt attachment/detachment detection switch comprises: a printed circuit board including a circuit for detecting attachment/detachment of a seat belt; a movable plate configured to slidably move along with insertion of a tongue plate of the seat belt; a rotor including a lever coupled to the movable plate, the rotor being rotatably attached to the printed circuit board to rotate as the tongue plate is pushed into a buckle; and an electric brush attached to the surface of the rotor that faces the printed circuit board, the electric brush having leg parts that change a state of contact/non-contact with a conductive part of the circuit in accordance with a rotating state of the rotor.
