We have a customer requesting a polyester dome switch on a flex circuit. I
have questions out to our Flex Fab vendors, but thought I'd also ask here.
Are these done during the fabrication process? Will the vendors fab these
in? Or are they installed after? How do these effect the standard flex
circuit materials? The flex circuits in question intended use is Continuous
Flex. I've found mfg's of these switchs, though am having trouble finding
how they are implemented.

Thanks in advance for any assistance.
