A seat belt attachment/detachment detection switch including 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.

Seat belt attachment/detachment detection switch

A seat belt fastened/unfastened state detection switch includes: a printed substrate that includes a circuit for detecting a fastened/unfastened state of a seat belt; a rotor that is rotatably attached to the printed substrate, includes a contact portion, the contact portion coming into contact with a tongue of the seat belt, and rotates in a forward direction in accordance with pushing of the tongue into a buckle; a spring that makes the rotor, the rotor being in a rotated state in the forward direction, rotate in a reverse direction in accordance with pulling of the tongue from the buckle; and an electric brush that is attached to a surface of the rotor, the surface facing the printed substrate, and includes a leg portion whose contact/non-contact state with respect to a conductive part of the circuit changes depending on a rotation state of the rotor.

Seat belt fastened/unfastened state detection switch

An ON/OFF detecting buckle switch includes: a case in a housing shape; a substrate fixing member equipped in an inner side face of the case; a slider insertion port equipped in an upper face of the case; a support portion equipped in an inner side face of the case; a first fixed terminal folded stepwise in a longitudinal direction of a strip shape to circumvent the substrate fixing member, having one end provided with a notched portion and the other end fixed to the inner side face of the case; a first movable terminal in a strip shape having one area fixed to the support portion; a slider provided with a terminal press portion that projects inside the case penetrating through the slider insertion port and the notched portion, and when pressed down, presses down an end of the first movable terminal; and a spring that biases the slider upward.

On/off detecting buckle switch

An ON/OFF detecting buckle switch includes: a case in a housing shape; a slider insertion port equipped in an upper face of the case; a support portion equipped in an inner side face of the case; a fixed terminal provided with a notched portion in one end in a strip shape and the other end fixed to the inner side face of the case; a movable terminal in a strip shape having one area fixed to the support portion; a slider provided with a terminal press portion that projects inside the case penetrating through the slider insertion port of the case and the notched portion of the fixed terminal, and when pressed down, presses down an end of the movable terminal; a spring that biases the slider upward; and bent portions in a hook shape in the notched portion of the fixed terminal and an end of the movable terminal.

A slide switch is provided that is more excellent in reliability than conventional techniques. A slide switch senses an extracted state and an inserted and engaged state of an object. The slide switch includes a body, a slider, a terminal, and an armature. The slider is slidably held in the body and is pushed by insertion of the object to slidingly move. The terminal is provided with a fixed contact point disposed on a surface, facing the slider, of the body along a sliding movement direction. The armature is attached to the slider and is provided with a moving contact point that slides on a fixed contact point disposition surface of the body in association with sliding movement of the slider. In the entire range of the sliding movement, the body and the slider cover all around the fixed contact point and the armature.

Slide switch

The slide switch includes a body, a slider, a terminal, and an armature. The slider is slidably held in the body and is pushed by insertion of the object to slidingly move. The terminal is provided with a fixed contact point disposed on a surface, facing the slider, of the body along a sliding movement direction. The armature is attached to the slider and is provided with a moving contact point that slides on a fixed contact point disposition surface of the body in association with sliding movement of the slider. The slider is provided with an engagement part to receive an action of a moving part that moves in the sliding movement direction in association with extraction and insertion of the object, and the engagement part is in shape of generating a free running distance in which the slider does not act even when the moving part acts.

A slider is slidably held in a body and is pushed by insertion of an object to slidingly move. Terminals are provided with fixed contact points disposed on a surface, facing the slider, of the body along a sliding movement direction. The armature is attached to the slider and is provided with moving contact points that slide on a fixed contact point disposition surface of the body in association with sliding movement of the slider. The slider has an armature mounting surface with a side wall protrudingly formed in one end in the sliding movement direction. The body has a facing surface facing an end surface of the side wall in an entire range of sliding movement. At least any one of an end in the sliding movement direction of the end surface of the side wall and an end in the sliding movement direction of the facing surfaces of the body has a foreign substance elimination groove formed therein.
