Product Description
Metal shrapnel (Shrapnel for short) (because its switch is like an upside-down pot, it is commonly called Guozi slice, or 'pot slice'), also metal dome in English, made of stainless steel, is an important part of the switch.
With the help of the conductivity, the metal shrapnel acts as a high-quality switch between the user and the product. At the same time, the stable resilience of the metal shrapnel (automatically reset after pressing) is leveraged.
Materials for making snap dome and triangle or four-leg metal dome membrane switch:
The metal keypad dome switches and snap dome are sure to be the switch button. If the various switches are separated from the Metal Domes, it loses its meaning, so it is said that the Metal Domes plays a key role in the switch, and it was later known as the metal dome switch and snap dome.
Application of a metal dome: used on button switches, membrane switches, tact keypads, self-locking switches, metal dome switches, and snap dome.
Function of metal dome membrane switch: to power on and off, which can give the operator good tactile feedback.
Originally, there is no professional name called snap dome in the early days. And a snap dome is made of metal material. Because it is a dome, it can bounce upward and be concave downward (convex and concave). Its initial state is convex upward, and it will concave downward when the operator exerts a force, and then rebounds after the force is removed. This kind of elastic metal material is uniformly called metal dome or snap dome. Later, when metal dome switches were introduced into China, many people were used to calling them metal dome switches. Metal domes also referred to as metal snap domes or tactile metal domes
Custom-made metal dome stickers of different shapes are widely used
There are four main shapes of Metal domes: triangle, circle, ellipse, and cross, with 1, 4, and 5 contacts on the top. The stickers of Metal domes should be customized according to individual needs, do not use them randomly, and avoid affecting the quality of the products. It is very convenient to assemble the stickers on the pot, and it is enough to attach a full version. Of course, pay attention to the stability of the conductive parts of the pot and the circuit board.
Metal domes are mainly in the size of 4MM, 5MM, 6MM, 7MM, 8MM, and 9MM. With a strength of 100-600gf (the strength depends on the customer's product needs), triangular pots are widely used and involve all aspects of our modern life.
The size of the pot is different. The strength can be set to large or small. If special requirements are required, special materials can be used. The strength can reach about 3000gf. The triangle has three feet and a vertex. The legs of the triangular pan can be long and endless, these are determined by the needs of customers.
Metal domes are mainly used in circuit boards, tact switches, micro switches, key switches, pc boards, and other products. It has the characteristics of stable contact, good continuity, and excellent rebound feel. The triangular pan-shaped piece is an excellent accessory used in major electronic products.
About the pot pieces:
The pot pieces can be tinned, silvered, gold-plated, and other different surface treatments. Different treatments on the surface can produce different effects. For example, tin plating can solve the problem of heating without fading. In addition, gold plating and silver plating on the surface will increase the pot pieces Gloss has a certain resistance effect.
About the pan-shaped pieces:
The pan-shaped pieces are generally made by customers with drawings provided by us. The types of pan-shaped pieces most used by the guests are round pieces and oval-shaped pieces, also known as waist-shaped pieces and cross-shaped pieces. Triangular pan slices and rectangular pan slices have diameters from 3mm to 20mm, strength from 100gf to 600gf, and special strength pans can reach 6000gf.
The back of the pan-shaped piece can be dotted or not, the round pan-shaped piece is generally five contacts, and one contact, some special needs no contact. In order to facilitate assembly, the pot pieces are generally stuck together with PET, which not only facilitates assembly but also accurately positions.
About its different names:
Metal domes are also known as metal shrapnel. Its English name is meal Dome slices. Sometimes people will say membrane switches. The name of Metal domes is generally based on his purpose. The ones commonly used in industry are called The shrapnel, and used in mobile phones, the keyboard is called the potsticker, and the switch series is called the membrane switch. Single-layer potstickers are generally full-page stickers.
Advantages: agile operation, fast assembly, disadvantages: bad experience for customers, no dustproof function, easy to be invaded by dust, and cause contact problems. Therefore, the single-layer pot-shaped pieces are becoming smaller and smaller in the market. Only when the Tiebei sealed machine does not require the protection and operation of the pot-shaped pieces, the whole-plate stickers and single-layer structured pot-shaped pieces will be used. The advantages of Double-layer film potstickers are: dustproof, durable, good feel, etc.
As a metal dome switch supplier, we can offer various metal dome switch solutions, especially for tactile membrane keyboard and PCB. If you need customized shrapnel, please contact us, as a membrane switch product factory, we can also export customized metal dome layer according to customer needs.
