New description: [New technical field] This creation is to provide a two-stage tact switch and its conductive shrapnel, especially a switch that produces two-stage conduction function during pressing and its conductive shrapnel. There are two actions for electronic products. [Prior Art] Two-stage tact switches are commonly used in digital cameras to provide focus after the first segment is turned on, and to provide shutter opening after the second segment is turned on. The inside of the switch usually requires two pieces of laminated metal shrapnel to play the role of two-stage circuit conduction. The metal shrapnel below is usually open, for guiding the contacts of the first section, and the center point of the upper metal shrapnel is worn. Pass the metal shrapnel underneath and abut the contacts of the second section. The top and bottom surfaces of the conventional metal shrapnel and the bottom surface of the upper metal shrapnel are generally required to be plated with a metal layer having good electrical conductivity, so that the cost cannot be effectively reduced. In summary, the creator feels that the above-mentioned deficiencies can be improved. He has devoted himself to research and cooperates with the application of academics, and finally proposes a design that is reasonable in design and effective in improving the above-mentioned deficiencies.

Please refer to the figure] and Fig. 3, Fig. 3 is a top view of the insulating body and the terminal in the present invention. In this embodiment, the first terminal 14Α, the second terminal 14β, the third q 14C and the fourth are buried and incident. The terminal 14D is inside the insulating body 12. Therefore, a plurality of mold fixing holes are formed to form a plurality of holes. The terminals are fixed during the molding process. Each terminal is _-(four) in the J-board of the Wei-edge body. The first terminal MA and the third terminal == extend into the accommodating portion 22 and the 右 右 right 鳊The scorpion 14C1, 〇 又5 has a portion of the contact portion MA1 and the end of the fourth portion 4β extends into the accommodating portion 22 and is located at the portion. In the fourth embodiment, the second section of the contact portion ΗΒ1 1 line ^^ contact portion is between 4A1 and 14C1, and the three are generally cultivated. The read ring ^Zou 2 elastic piece 20 has a weir portion 22, and a plurality of pins 222 are connected to the read ring portion: the bucking edge extends outward, and the strip portion 224 is connected to the ground by four slots, inner, ' Cheng. The pin 222 is correspondingly disposed in the '0'. The annular portion 22 is located above the first segment contact portions ΗΑ1 M432126 and 14C1, and the strip portion 224 is located just above the second segment contact portion. The pins of the conductive elastic piece 2 are twisted by the annular portion 2, and the annular portion 22 is inclined upward from the outside to the inside. The strip portion W has an arc shape of 2. The two sides of the strip portion 224 of the conductive elastic piece 2G are away from the two-section contact portions HA1 and 14C1; or the strip portion 224 is substantially perpendicular to the first-stage contact portions I4A] and 14Cl and == = straight line. The intermediate point of the strip portion 224 is such that the spring 30 is disposed in the receiving portion 122 and is located on the conductive elastic clip. With the following description of the operation of the present embodiment, it can be understood that the Bosch 30 of the present invention is not limited to the metal piece, and is only used to press the conductive elastic piece. The insulating film 40 covers the receiving portion of the insulating body. To prevent moisture and dust from entering the base (1). The cover body 5 () is the top surface of the insulative housing 12, and the top surface 52 of the cover 50 is formed as an opening a/.
