Abstract

A switch device includes, a movable terminal including a snap action mechanism that bends a spring when a user moves an operating portion, a first fixed terminal that contacts the movable terminal when the spring is not bent, a second fixed terminal that contacts the movable terminal when the operating portion is moved by a specified amount to bend the spring, a case including an opening, and a cover that closes the opening and is separate from the first fixed terminal. When the opening is closed by the cover, the first fixed terminal is positioned in the case by the cover.

First claim

What is claimed is:

1. A switch device, comprising:
a movable terminal including a snap action mechanism that bends a spring when a user moves an operating portion;
a first fixed terminal that contacts the movable terminal when the spring is not bent;
a second fixed terminal that contacts the movable terminal when the operating portion is moved by a specified amount to bend the spring;
a case including an opening;
a cover that closes the opening and is separate from the first fixed terminal, wherein when the opening is closed by the cover, the first fixed terminal is positioned in the case by the cover; and
a press-fitting mechanism that temporarily fixes the first fixed terminal to the case when the first fixed terminal is press-fitted to the case.

2. The switch device according to claim 1 , further comprising:
a temporary holding portion that temporarily fixes the cover to the case, the cover being coupled to the case to close the opening.

3. The switch device according to claim 1 , wherein the cover includes a rear surface including a compressible rib that presses the first fixed terminal from above when the cover is temporarily fixed to the case.

4. The switch device according to claim 1 , wherein the first fixed terminal includes:
a first fixed terminal body that contacts the movable terminal; and
a first fixed terminal connection pin that is arranged at an end of the first fixed terminal body and configured to be mounted on a board, and
the first fixed terminal connection pin is bent in advance in a direction parallel to a mounting surface of the board before the first fixed terminal is coupled to the case.

5. The switch device according to claim 1 , wherein the press-fitting mechanism temporarily fixes the first fixed terminal to the case by press-fitting proximal ends of the first fixed terminal to the case.

6. The switch device according to claim 5 , wherein the first fixed terminal includes:
a first fixed terminal body that contacts the movable terminal, wherein the first fixed terminal body is C-shaped, the proximal ends of the first fixed terminal are two proximal ends, which are opposed to each other, of the first fixed terminal body; and
two first fixed terminal connection pins that are respectively arranged at the two proximal ends of the first fixed terminal body and configured to be mounted on a board.

7. The switch device according to claim 6 , wherein each of the two first fixed terminal connection pins is bent in advance in a direction parallel to a mounting surface of the board before the first fixed terminal is coupled to the case.
