Switch

The switch according to 1, further comprising a light guiding body, wherein:

• the light guiding path includes a first light guiding path and a second light guiding path, the first light guiding path and the second light guiding path being disposed parallel with each other and spaced apart from one another at an interval in a displacement direction of the movable member;
• the light guiding body is structured to disperse light emitted from the light emitting element to be guided respectively to the first light guiding path and the second light guiding path;
• the first light guiding path is disposed in a position such that the first light guiding path receives light emitted from the light emitting element passing through the through hole when the movable member is arranged in a first predetermined position via the operation of the knob;
• and
• the second light guiding path is disposed in a position such that the second light guiding path receives light emitted from the light emitting element passing through the through hole when the movable member is arranged in a second predetermined position via the operation of the knob.

A switch comprising:

• a movable member displaceable in association with an operation of a knob, the movable member including a through hole penetrating therethrough in a thickness direction of the movable member;
• a light emitting element arranged on one side of the movable member in the thickness direction;
• a light guiding path arranged on the other side of the movable member in the thickness direction such that the light guiding path receives light emitted from the light emitting element passing through the through hole when the movable member is arranged in a predetermined position via the operation of the knob;
• and
• at least two light receiving elements attached to the light guiding path.

The switch according to 12, further comprising a light guiding body, wherein:

• the light guiding path includes a first light guiding path and a second light guiding path, the first light guiding path and the second light guiding path being disposed parallel with each other and spaced apart from one another at an interval in a displacement direction of the movable member;
• the light guiding body is structured to disperse light emitted from the light emitting element to be guided respectively to the first light guiding path and the second light guiding path;
• the first light guiding path is disposed in a position such that the first light guiding path receives light emitted from the light emitting element passing through the through hole when the movable member is arranged in a first predetermined position via the operation of the knob;
• and
• the second light guiding path is disposed in a position such that the second light guiding path receives light emitted from the light emitting element passing through the through hole when the movable member is arranged in a second predetermined position via the operation of the knob.

A switch comprising:

• a movable member displaceable in association with an operation of a knob, the movable member including a through hole penetrating therethrough in a thickness direction of the movable member;
• a light emitting element arranged on one side of the movable member in the thickness direction;
• a light guiding path arranged on the other side of the movable member in the thickness direction such that the light guiding path receives light emitted from the light emitting element passing through the through hole when the movable member is arranged in a predetermined position via the operation of the knob;
• and
• at least one receiving element attached to the light guiding path;
• wherein the movable member is swingable around a rotational shaft in parallel with a rotational shaft of the knob, the movable member rotatable from a reference position in a direction based on a rotational direction of the knob via an operable element extending from the knob.
