Niceone-tech is a professional (HMI) human machine interface control module manufacturer . Niceone-tech has always been people-oriented, and should constantly improve the working environment and living environment of employees, so as to enhance the centripetal force of employees to the enterprise so that employees can concentrate on their work. Because of this, although Nicone-tech is now only a 70-person factory, our staff is very united. Over the past five years, Niceone-tech has developed a variety of membrane switches, silicone rubber products, and the plastic that has been sold to different countries and has been well received by customers. All this is inseparable from the efforts of each of our personnel. We also provide membrane switch, membrane keypad, graphic overlay, silicone rubber keypad,etc.
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 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 tactile switches and dome switch pcb.
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 switches: 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.
