Metal shrapnel, which is made of stainless steel plate, is a main component of the button. With the basic law of metal shrapnel, it has the effect of a high-quality control switch between staff and equipment. At the same time, using the relatively stable resilience of the metal shrapnel (automatic return after pressing and holding), and a long service life, give the operator high-quality tactile feedback. The shrapnel key is used in the membrane keys of rigid boards such as printed circuit boards. The editor of Delgao below will introduce some disadvantages of metal shrapnel in the whole process of application.

Metal shrapnel without some, such as ring shrapnel, waist shrapnel diameter 4mm, 5mm such metal shrapnel, most of them are used in small power switches, mobile phones, controllers and other commodities, there are also cross-shaped shrapnel, such as diameter 6mm to 12mm , Most of them are used on membrane keys, PCB boards and other products. The on-off performance of the metal shrapnel conductive film of this product is very high. This product is manufactured in the purification workshop, but it is difficult to If you choose Without some metal shrapnel, the surface of the metal shrapnel and the route is very large. If dust enters, the failure rate of the on-off performance of the metal shrapnel will increase.

The metal shrapnel with some has a raised point in the middle. This product only touches a point in the middle of the metal shrapnel and the line. When dust enters, the dust will also be around the protrusion, not. It is easy to stick to the bumps. If there is dust on the bumps, you can press twice more to make the dust fall off and break automatically. This reasonably reduces the failure rate of the conduction performance, and at the same time, the metal shrapnel can also achieve the on-off performance specified by the standard. In this way, the failure rate of the on-off performance of the metal shrapnel is reduced.

As the use of torsion springs becomes more and more common, the requirements for the diversification of the technology and equipment of torsion spring parts are also becoming higher and higher. Anyone who needs metal shrapnel, dome pieces, etc. can contact Delgo.
