FPC membrane switch

The difference between FPC membrane switches and ordinary membrane switches is that the circuit is no longer a silver paste printed circuit, but a more stable FPC circuit material, which is more resistant to high temperatures and corrosion. FPC membrane switch circuit layer uses FPC flexible circuit board. This circuit has high precision, minimum output spacing of 0.5mm, low resistance value, more stable circuit function and longer service life.

For the flex circuit membrane switches, there are two types: Silver printed PET circuit and copper etched FPC circuit.Their difference and advantages & disadvantages are listed bellow:

Items	Silver Printed Circuit	Copper Etched FPC Circuit
Material	PET (Polyester)	Polyimide
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	Normal	Very low
Cost	low	high
Lead Time	12-15 working days	12-15 working days
Pitch	1.0mm,1.27mm,2.54mm	0.5mm, 1.0mm,1.27mm,2.54mm

FPC membrane advantages compared with silver film switch
1.Low resistance(10% of silver film switch)
2.load large current(Normally 1Acurrent/0.5mm line)
3.Components(LED and resistance)can be welded more firmly
4.Good oxidation resistance, suitable for humid environment
5.The connector at the end of cable can be made to smaller to save space.

FPC Membrane Switch design options:

Single-sided – conductive traces one side copper of the film substrate

Double-sided – conductive traces both sides copper of the film substrate

Rigid-Flex – a laminated combination of a Copper Flex switch with a rigid FR4 PCB membrane switch

Solder active and passive components into the switch design

FPC + MEMBRANE SWITCH + RUBBER KEYPAD

FPC+MEMBRANE SWITCH+ TOUCH PANEL

PCB+MEMBRANE SWITCH

WATERPROOF MEMBRANE SWITCH

Possible pitch 0.5mm and 0.3mm for ZIF connector

Plating options can be tin, nickel, or gold
