[0031] The shrapnel 6 is mainly used for conducting electricity, so the shrapnel 6 is made of a conductive material. Conductive materials refer to materials specifically used for transmitting and conducting electric current, and are generally divided into two categories: good conductor materials and high resistance materials. Conductive materials include conductive plastics and conductive rubbers. Conductive rubber is made by evenly distributing conductive particles such as silver-plated glass, silver-plated aluminum, and silver in silicone rubber, and contacting the conductive particles through pressure to achieve a good conductive effect.

[0032] Button 3 is made of silicone material. Silicone is divided into solid silicone and liquid silicone. The raw materials are mainly divided into silicone rubber, silicone resin, silicone oil, and silane. Silicone rubber: mainly divided into room temperature silicone rubber and high temperature silicone rubber, with good electrical insulation performance, not easy to age, high adsorption performance, good thermal stability, stable chemical properties and other characteristics. It is also the most common material among silicone products. Silicone resin: It is a mixture of atomic structures of methyltrichlorosilane, phenyltrichlorosilane, and diphenyldichlorosilane. Generally, other hydrocarbon groups are connected to silicon atoms. Silicone resin has excellent water resistance and temperature resistance. Silicone oil: It is made by dissolving dimethyldichlorosilane in water and then putting the ring body, capping agent, and catalyst together to obtain a mixture of various polymerization degrees. After the final filtration and decompression, silicone oil is obtained. Silane: It has a combustion chemical reaction with oxygen. It is a combination of silicon and hydrogen. It is mainly made from gas sources and can be used to make high-purity polycrystalline silicon, single crystal silicon, microcrystalline silicon, amorphous silicon, silicon nitride, silicon oxide, heterogeneous silicon, and various metal silicides. It is usually used in optoelectronic technology, solar energy, batteries, and displays. Glass and organic glass plating are widely used in the current technological development. Silane has a very strong spontaneous ignition range and a wide combustion range. It is a highly dangerous gas.

[0033] The first platform 7-2-1 and the second platform 7-5-2 are provided on both sides of the connecting piece 5. The functions of the first platform 7-2-1 and the second platform 7-5-2 are: when the button is pressed, the middle of the spring sheet is pushed downward, and the middle of the connecting piece is pushed downward, and the normally closed contact points on both sides may bounce upward. In order to prevent the contact point from bouncing, the above two platforms are set, and the two platforms will hit the spring sheet.

[0034] A boss is provided at the center of the connecting piece 5. The boss of the connecting piece 5 is used to receive the elastic piece 6 when it is pressed down. The base 1 is provided with a step. The step of the base 1 is for supporting the connecting piece 5 and the elastic piece 6. A first protrusion 8 and a second protrusion 9 are provided on both sides of the connecting piece 5.

[0035] The working principle of the two normally open and two normally closed touch switch of the utility model is:

[0036] Press the upper outer part of the silicone button, and the internal boss of the silicone button will press against the middle part of the spring. After the spring is subjected to a certain pressure, it will instantly change from its original raised state to a recessed state, and quickly press against the central boss of the connecting piece. The connecting piece will drive the connecting piece to move downward, so that the connecting piece will contact the left and right welding copper feet, and connect the welding copper feet on both sides to achieve circuit connectivity.

[0037] When the button is not pressed, the third copper pin 4-3 contacts the concave part of the first connecting piece, and then contacts the spring through the 8-first protrusion on the connecting piece, and the fourth copper pin 4-4 contacts the concave part of the third connecting piece, and then contacts the spring through the 9-second protrusion on the connecting piece, so that the third copper pin 4-3 and the fourth copper pin 4 are closed. The concave parts on both sides of the second copper pin 4-2 and the fifth copper pin 4-5 are in contact with the concave parts on both sides of the connecting piece, so that the second copper pin 4-2 and the fifth copper pin 4-5 are in the normally closed state, and the rest of the points are normally open, 4-1, 4-4 are normally open, 4-3, 4-6 are normally open. In the initial state: 1, 4 are normally open, 3, 6 are normally open. 2, 5 are normally closed, 3, 4 are normally closed. When the button is pressed: so the circuit is normally closed.

[0038] When the button is pressed, the middle of the spring is concave and pressed against the connecting piece, which drives the connecting piece to press the copper foot, and all the connecting parts on both sides are normally closed.

[0039] The utility model has the beneficial effects of the design of the above embodiments as follows: by setting a base; a cover plate, which is arranged above the base and is used to cover the base; a button, which is arranged above the cover plate and is used to turn on or off the touch switch; a copper foot, which is arranged on the base; a connecting piece, which is arranged on the base; a spring, which is arranged above the connecting piece; and a connecting piece, which is arranged below the connecting piece; it can be applicable to touch switches of various sizes, and which circuit to use can be determined according to different needs, including but not limited to two normally open, three normally open, three normally open and one normally closed touch switches, etc., and multiple normally open can be achieved by adding an even logarithmic circuit in the middle.
