The fixed terminal is bent in the direction of arrow A' in FIG. After fixing the fixed contacts 10 and 13 to the contact support parts 9 and 12 of 8 and 11 by spot welding, the upper parts of the fixed terminals 8 and 11 are attached to the bottoms of grooves V 2 and V 3 that are perpendicular to the striped parts 2. and dashed-dotted lines B and C passing through approximately the center of the contact support parts 9 and 12.
Then, bend it in the directions of arrows B' and C' in FIG. 9 so that the contact support parts 9 and 12 are vertically opposed to each other. At this time, the center of the contact branch holding parts 9 and 12 is the center of the anchor part 4 of the common terminal 3 and the center line CL.
(See Figure 3 or Figure 6). That is,
The contact support parts 9 and 12 of the fixed terminals 8 and 11 are bent along the dashed lines B and C and punched out so as to face each other vertically about the center line CL as shown in the developed view shown in FIG.

とすることができる。 Furthermore, the anchor part provided at the tip of the common terminal 3 is bent in the thickness direction of the common terminal 3 on a line passing approximately through the center of this anchor part, and the contact provided at the tip of the pair of fixed terminals 8 and 11 is bent. support part 9,
10 is bent so that the contacts 10 and 13 face each other in the vertical direction on a line passing approximately through the center of the contacts 10 and 13, so that the common terminal 3 and the fixed terminals 8 and 11 are molded and positioned at the center of the insulating stand. It is also possible to eliminate problems such as poor insulation and short circuits. Moreover, since the above-mentioned bending is only done once for each terminal, and the bending is also done at the tip of the terminal, errors between contacts and between terminals can be minimized, resulting in highly reliable microcontrollers. It can be a switch.

ができるという効果を有する。 As is clear from the above description, according to the present invention, an anchor part that has a groove for engaging the movable coloring piece and projects in a substantially rectangular shape through a cut groove parallel to the stripe is attached to the distal end of the anchor part. A pair of fixed terminals are provided at the distal end of the common terminal and a contact support part that protrudes in a substantially rectangular shape through a cut groove perpendicular to the striped part, and both contact support parts are provided so as to face each other. a step of punching out a metal plate in a vertical direction from the top; a step of welding the fixed contacts to the contact support portions of the pair of fixed terminals; and a step of punching the contact support portions of the pair of fixed terminals through the cut grooves. A step of bending the anchor part of the common terminal on a line that is parallel to the striped part and passing through approximately the center of each fixed contact, and bending the fixed contacts so as to face each other in the vertical direction, and inserting the anchor part of the common terminal through the groove. a bending process on a line perpendicular to the anchor part and passing approximately through the center of the anchor part; a resin molding process of resin molding the central part of each terminal; and a process of separating the common terminal and fixed terminal from the muscle part. Therefore, the manufacturing process is simple, as each terminal only needs to be bent once. Furthermore, since the anchor portion is wide, the movable piece is supported stably. In addition, since the fixed contacts are mounted on the flat plate of the fixed terminal, contact reliability is not only improved, but also the bendable contact holder is at the tip of the fixed terminal, so the spacing between the fixed contacts can be kept constant. This has the effect that a microswitch with stable switch characteristics can be obtained.
