Abstract

The present invention is to provide a vehicle door switch that is capable of adjusting the amount of movement made by a rod with ease and a method for attaching a vehicle door switch. A vehicle door switch includes a rod configured to move as a door is closed, a detecting unit configured to output a detection signal when one of ends of the rod has moved by a predetermined distance or more, and a limiting unit configured to limit the amount of movement made by the rod within a range where the detecting unit outputs the detection signal.

First claim

What is claimed is:

1. A vehicle door switch comprising:
a rod configured to move as a door is closed;
a detecting unit configured to output a detection signal when one of ends of the rod has moved by a predetermined distance or more; and
a limiting unit configured to limit an amount of movement made by the rod and corresponding to a range where the detecting unit outputs the detection signal to a limited value that is shorter than a prescribed initial value.

2. The vehicle door switch according to claim 1 , wherein the limiting unit is configured as a spacer for limiting the amount of the movement to be made by the rod and attached to a housing that supports the rod in a movable manner.

3. The vehicle door switch according to claim 1 , wherein the limiting unit is provided on the rod as a protrusion for limiting the amount of the movement to be made by the rod.

4. The vehicle door switch according to claim 1 , wherein the limiting unit changes a position at which the detecting unit is positioned, relative to a housing on which the detecting unit is provided.

5. A method for attaching a vehicle door switch, comprising:
attaching a vehicle door switch to a vehicle, the vehicle door switch including a rod configured to move as a door is closed, a detecting unit configured to output a detection signal when one of ends of the rod has moved by a predetermined distance or more, and a limiting unit configured to limit an amount of movement made by the rod and corresponding to a range where the detecting unit outputs the detection signal, to a limited value that is shorter than a prescribed initial value; and
adjusting a position of a pressing unit provided on the door, the pressing unit being configured to press the rod.
