For the flex circuit Membrane Switches, there are two types. They are silver printed PET circuit and copper etched FPC circuit. Their difference and advantages&disadvantages listed bellow:

Items	Silver Printed Circuit	Copper Etched FPC Circuit
Material	PET (Polyester)	Copper
Conductor	Printed silver	Copper
Contact Fingers	Silver and Carbon	Gold plated
Contact Buttons Pads	Silver	Gold plated
Life & Reliability	normal	good
Stability	normal	good
Resistance	low	Very low
Cost	low	high
Lead Time	2-3 days	7-10 days
Pitch	0.5mm (not suggested), 1.0mm,1.27mm,2.54mm	0.5mm, 1.0mm,1.27mm,2.54mm

Usually if the membrane switches need assembled many LEDs, then we suggest to use FPC circuit, it can get more stable LED soldering quality. For the normal application the PET circuit is enough, which is more economical. In addition if the conductor pitch is 0.5mm, although we also can print it, but we still suggest to use FPC circuit. Because of that 0.5mm pitch is too small and it is easy to occur the short circuit problem.
