  • Product performance description

  • 产品性能介绍说明

Our tactile metal domes are momentary switch contacts that, when used in conjunction with a printed circuit board, flex circuit,or membrane, become normally-open tactile switches. Tactile metal domes are placed on printed circuit boards by means of
pressure-sensitive adhesive tape or they are captured in a pocket design.





Product Usage


    • PCB Pads Usage

* Via hole through the board is suggested for venting if other means are not used

* HUIHUI recommends that the circuit area under the dome be void of solder mask. The keep out area begins at the outside edge
of the outer circuit pad that the dome is positioned on and includes area inside of the pads.

FAQ


Q. Can the domes be soldered to a circuit board?
A. Not recommended. When the domes are pushed, the feet actually move outward slightly. When soldered to a circuit board, the feet of the domes are restricted from their natural movement. This restriction can negatively affect the tactile response of the domes,and in some cases, cause irreparable damage to the domes or break the solder joint.

Q. What is the purpose of a dimple in the center of a dome?
A. Various Snaptron domes have a dimple located in the center of the dome. Typical depth of the dimple is .001” to .002” but may vary depending on the dome style. A dimple is used to reinforce or improve the dome contact with the PCB.
