Abstract

A slide switch installed in a buckle apparatus includes a body 20, a slider 30 held slidably in the body 20, the slider 30 sliding when pressed by a movable part of the buckle apparatus, fixed contacts 41 to 43 placed in a direction in which the slider slides, on a surface of the body 20 that faces the slider 30, a movable piece 44 sliding on the surface of the body 20 on which the fixed contacts 41 to 43 are placed. The slider 30 has a size that obscures the fixed contacts 41 to 43 in the entire range in which the slider 30 slides. The fixed contacts 41 to 43 are unlikely to be affected by foreign matter etc. and adherence of foreign matter that degrades performance can be prevented.

Claims

1. A slide switch installed in a buckle apparatus, comprising:

a body;

a slider held slidably in the body, the slider sliding when pressed by a movable part of the buckle apparatus;

a fixed contact placed in a direction in which the slider slides, on a surface of the body that faces the slider, and

a movable piece sliding on the surface of the body on which the fixed contact is placed as the slider slides;

wherein the slider has a size that obscures the fixed contact in an entire range in which the slider slides.

2. The slide switch installed in a buckle apparatus according to claim 1, wherein grease is applied to the fixed contact.

3. The slide switch installed in a buckle apparatus according to claim 1 or 2, wherein the fixed contact is formed in the body by insert molding.

4. The slide switch installed in a buckle apparatus according to claim 1 or 2, wherein the movable piece has a pair of feet, there are a first fixed contact, a second fixed contact, and a third fixed contact, the fixed contact being one of the first, the second, and the third contacts, the first fixed contact extends in a sliding path of one of the pair of feet, and the second fixed contact and the third fixed contact extend in sequence in a sliding path of the other of the pair of feet.

5. The slide switch installed in a buckle apparatus according to claim 1 or 2, wherein the slider has an engaging hook on either side in a width direction orthogonal to a slide direction of the slider, the slider being held by the body through the engaging hook.

6. The slide switch installed in a buckle apparatus according to claim 1 or 2, wherein a spring for returning the slider is present between the body and the slider.
