New description: f new technology field] The present invention is to provide a two-stage tact switch and its conductive shrapnel, especially a switch that generates two-stage conduction function during pressing and its conductive shrapnel 'available Electronic products produce two kinds of actions. [Prior Art] The two-stage tact switch is small in size and is commonly used in digital cameras to provide focus after the first segment of the circuit is turned on. The second segment of the circuit is turned on to provide a shutter open function. 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-shaped to open the contacts of the first section. The center point of the metal shrapnel above. Pass through the metal shrapnel below and abut the contacts of the second section. .... After the metal shrapnel is pressed, if there are foreign particles inside, no matter where the impurity particles are located, it is easy to cause poor contact of the metal shrapnel. 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. [New content] The present invention aims to provide a two-stage tact switch and a conductive elastic piece thereof, which is to reduce the contact failure condition to improve the conduction yield of the switch. To achieve the above, the present invention provides a two-stage tactile switch that includes a base, two conductive springs, a reed, an insulating film, and a cover. The base has an insulating body and a plurality of terminals fixed in the insulation 3/12^; the top surface of the insulating body is recessed-receiving portion, and the receiving σ[5] forms a plurality of pin grooves The terminals extend into the accommodating portion η to form at least two first segment contact portions and a second segment contact portion. The conductive strip has a weir, and a plurality of pins are outwardly extended from the outer edge of the annular portion and the strip is connected across the inner edge of the annular portion. The wide-legged foot is correspondingly placed in the pin grooves, and the annular portion passes through the portion. Above the upper first contact portions, the protrusions are correspondingly located above the 5? contacts. The * piece is disposed in the receiving portion and located on the guide and the elastic piece. The insulating film covers the receiving portion of the insulating body. The cover plate is fixed to the top surface of the insulating body, and an upper surface thereof forms an opening.
