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.
