In the second use case of such a switching device, the external terminals 1 1 2 are placed on the flat portion 1 1 2 a on a solder paste before melting, and sent to a reflow furnace, where they are placed in the furnace. Heating, that is, as shown in FIG. 11, some molten solder will also adhere to one surface of the upright portion 1 12. However, because the flat portion 1 1 2 a of the terminal 1 12 is short and the contact area with the solder paste is small, The amount of molten solder that can be attached to one surface of the upright portion 1 1 2 b is not too much. Therefore, in order to make the terminal 112 have sufficient strength to the soldering strength of the printed substrate 113, in other words, the conduction of the soldering layer 115 is conducted. For reliability and reliability of mechanical strength, it is preferable that molten solder is also adhered to the side surface 1 1 2 c of the flat portion 1 1 2 a. However, in the case of the second conventional product, the side wall 111b of the synthetic resin box 111 has a property of repelling molten solder. Therefore, as shown in FIG. 11, the protruding amount from the side wall 1 I 1 b is small. It is almost impossible to adhere the molten solder to the side 1 1 2 c of the flat portion 1 1 2 a of 1 1 2, so it is very difficult for the molten solder to invade the upper portion of the flat portion 1 1 2 a, so having the terminal 112 and The contact area of the solder layer 1 15 is insufficient, and it is difficult to obtain high reliability. Furthermore, in the third conventional example, in order to improve the solderability of the bent portion 1 2 9 c of the leg portion 2 ya of the cover, the full application of tin plating to the cover 1 2 9 will improve the switch. The cost of the device. In addition, the switch device of the third conventional example is provided with the ground portions 1 2 9 on both sides of the cover 1 2 9 facing the ground for soldering to the ground pattern 1 32 of the printed circuit board 130. , Along the paper size of about 1 2 5 of this paper, using the Chinese national standard (CNS) A4 (210XW7 mm) ^ ~ (Please read the precautions on the back before filling this page) Order J 444523 A7 B7 Economy Printed by the Consumer Probation Cooperative of the Central Procurement Bureau of the People's Republic of China. 5. Description of the Invention (9) The outer side of the side wall is bent downward to extend the tip of the foot 1 2 9 a, and the bent part is formed by folding at a right angle outward. 1 2 9 c. Therefore, when the shame 1 2 9 is made by stamping, the upper surface 1 2 9 e of the cover 1 2 9 is integrally processed to form a sheet of iron plate, and the legs 1 2 9 a are provided on both sides, and the The bent portion 1 2 9 c therefore has a poor yield of the cover material and leads to high costs. The present invention was developed in view of the problems of the conventional technology described above, and an object of the present invention is to provide a method for promoting cost reduction by simplifying a molding die or improving assemblability, and is also advantageous for miniaturization, and can improve the connection terminal to a printed circuit board. The soldering strength of the switch device can also improve the yield of the material. [Means for Solving the Problem] The above object of the present invention is to provide an integrally molded sheet having a common contact terminal, a fixed contact terminal, and an external connection terminal, and an insulating rod that can rotate the sheet. ; And the elastic contact crimped to the common contact, which is mounted on this rod, and is constantly elastically crimped to the fixed contact terminal, and the movable contact is allowed to leave; and the torsion coil spring which often springs the rod in a prescribed direction, And the part of the movable contact which is in elastic contact with the common contact is formed as, for. The slide will be from the end of the 1 end_back_-connected-to the wave with the same contact terminal surface curvature; ^ Board department can be achieved. ν *...

Description of the invention (10) The rotation direction of the rod, which uses the plucking force of the sliding portion as its rotational force, and the torsion coil spring The plucking force is constituted by the rotation direction of the rod in which the rotation direction of the rod is the same direction, which is appropriate. Moreover, the box made of synthetic resin forming the outer shell, and the terminals connected to the external terminals standing out from the green part of the bottom of the box and standing along the side wall of the box are soldered to the printing. In the switching device of the solder joint region of the substrate, a cutout portion can be achieved by providing a side surface of the base end portion of the terminal located on the bottom wall edge portion of the side wall of the case. In order to solve the above problems, it is adopted: a case made of synthetic resin, a conductive terminal provided for external connection provided in the case, and a metal part provided with a foot mounted on the case In the switch device constituted by the cover, the above-mentioned conductive terminal is soldered to the circuit pattern of the printed substrate, and the tip of the leg portion of the cover is in contact with the ground pattern of the printed substrate.

The description of the invention (Π) The sharpened end. [Function] The past is connected to the flat plate by a movable contact clip. The structure of the common contact is changed as described above. The bottom surface of the sliding portion of the movable contact is slid onto the common contact, so that as the rod rotates, the sliding portion slides on the common contact terminal. In this way, the common contacts such as a semi-spherical shape can be protruded at the bottom of the sheet, so the forming die of the sheet can be simplified. At the same time, when the rod is incorporated into the sheet, it is not necessary to move The two ends of the contacts are widened, which can improve the assemblability. Furthermore, the plucking force of the above-mentioned sliding portion that is plucked to the common contact terminal will be applied to the rod, and the plucking force can be stressed on the rotation of the rod Recovery force, so the plucking force is smaller Under the torsion coil spring, a large rotational restoring force can be sufficiently obtained. When the side of the base end portion connected to the outside is exposed in the cutout portion provided on the side wall of the box, it is not necessary to increase the slave box of the terminal. Under the protruding amount of the body, the side of the terminal outside the side wall of the box can be added to the side of the terminal that can be placed on the solder land, so the molten solder on the side wall away from a certain degree is very accommodating Attached to the side of the terminal, and the molten solder can easily invade the terminal at the same time, so the contact surface of the solder can be greatly increased. Furthermore, by abutting or nearing the tip of the cover to the printed circuit board The grounding pattern will discharge the static electricity charged to the switch device. Therefore, no soldering is required between the tip of the cover and the grounding pattern of the printed circuit board. It is also used in this paper.
