Why the customer want to make an\u00a0plunger or actuator<\/a>\u00a0\u00a0on the top layer of\u00a0metal dome array?<\/p>\n\n\n\n

There are two main functions:<\/p>\n\n\n\n

1. Increase the total height of overall product;<\/p>\n\n\n\n

2. Increase the touch and click feeling of dome switch.<\/p>\n\n\n\n

The height and diameter of the plunger or actuator should be based on the diameter of the tactile dome, and need to make a tooling for plunger making.<\/p>\n\n\n\n

But at the same time, we need to pay attention for below issues when making plunger or actuator.<\/p>\n\n\n\n

  1. It\u2019s better to make the height of plunger or actuator under 1mm, then the defect rate is very low.<\/li>
  2. If the height of plunger is larger than 1.0mm, the defective rate will be 20% to 30% more than the usual 1mm.<\/li>
  3. The poor performance is mainly a small bubble inside a, can be seen by visual.<\/li>
  4. There are also some bubbles around edge, this will cause the plunger to fall off with a gap.<\/li><\/ol>\n\n\n\n
