Applications:
1. A. For measuring device, such as analytic instrument, nautical intrument , medical equipment and so on
B. For mechanical and electrical products such as CNC machine electric weighing ,robot ,printing machine, function keyboard, monitor, printer, graphic plolter and so on .
C. For OS office system , such as telephone set ,fax machine, copy cat ,counter and so on
2. Note:
Metal dome’s feet can’t be folded 90 degree toward its top when use , it will reduce the life span of metal dome
Why to choose Shenzhen boerzhuo membrane switches?
1. No need to worry about the qualities (We take response if our reason lead failure ).
2. Any products in our factory are did life span test ,circuit test ,every step is in good quality control ,we insist on ,quality is depend on the making step not the QC workers ..
3. We are specialized ,can help to design and make good suggestion .
4. Except membrane switch and touch screen, we can also do different types of assembly, such as membrane switch and touch screen with FPC, PCB ,silicone rubber ,metal backer ,plastic bezel and so on.
5. We can accept small quantity order and offer competitive price.
6. Strict quality inspection ,100 % function testing ,and we can also do specified testing ,such as humility testing ,life expectancy testing ,actuation force testing.
A: What’s the lead time for sample and mass order ?
B: 7 Days is okay after drawing confirmed for sample ,mass order usually 15-20 days ,depend on the products..
