Tactile dome switches manufacturer in China

Tuesday, February 23rd, 2010

Tactile dome also name metal dome,snap dome,we are the leading of tactile metal domes switches manufacturer in china since 1999.

Normally, the tactile domes named by the America suppliers, such as Nicomatic, Snaptron. It means the click feeling, when you press down the dome, it will be closed the circuit and work. So I think it’s the interesting name.

The metal domes we made are also the same as tactile domes, such as our cross metal domes, the life cycles also can reach one million times. & we also can make the dome array. But for the costing, it’s much lower than theirs in America.We have exported our product wordwild, and win their trust.

Ok, If you have interested in our tactile domes and dome arrays, please contact us for the samples to evaluate. I’m sure you will like them.

The theory of metal dome work

Sunday, January 17th, 2010

This time follow me to know the details of the theory of metal dome work. Do you know how can it be worked? Ok, please see the below picture, I think it can very helpful for you to understand it.

The metal domes are placed on the printed circuit board by means of adhesive film tap or legs. When you pressed, the metal dome click down and contact with PAD of printed circuit board, and then closed the circuit. This is the theory of metal dome work.

The depth of dimple of metal dome

Tuesday, December 15th, 2009

Someone want to know the depth of metal dome, they think that the depth is the deeper the better, and it will be with the better click feeling. Yes, it will be a little better. But if the dimple is too deep, it will affect the life of metal dome. So it’s not the deeper the better.
In fact, As a leading snap dome manufacturer in China, we are very strict about the depth of dimple, it’a almost the stable for the depth.  We can’t change it as customers’ required as we have already set up the tooling. The metal dome life is very stable and can reach one million times.

The difference of three kinds plating of metal dome

Tuesday, October 13th, 2009

Recently, some customers have some queries about the plating of metal dome(snap dome) and the difference of them. We now have three kinds plating: Nickel plating, Silver plating, and gold plating. And I explain the difference in details as below: The material of metal dome(snap dome) is made from stainless steel 301 from Japan and USA.

 As the customers’ requirements, we have the three types plating for metal domes: Nickel, Silver, and gold plating. hese three types are plating in the contact surface(we also have the double sided plating). Its main fuction is to reduce the contact resistance, and increase the conduction. The contact resistance: Gold plating<Silver plating <Nickel plating. Although the plating can reduce the contact resistance, it also can increase the cost. Especially the cost of gold plating will increase several times.

Generally speaking, the resistance of our stainless steel is less than 10 ohm, the Nickel plating is less than 1 ohm. If you haven’t the special requirements for the resistance, we recommend you to use the stainless steel metal dome. Last, what the kind of product you would like to use is based on your product’s required. So it depends on your requirements.

OK, if you want to know more information, please contact us or see our FAQs.
