PCB Membrane Switches are generally more costly than Silver Flex Membrane Switches, they enjoy several advantages over Silver Flex switches:
- Lower electrical resistance/higher conductivity.
- Hard soldering components on a PCB is a more robust method to attach components vs. epoxy silver paste.
- Soldering many component types using automated pick-and-place equipment.
- Ideal for smaller designs where dense circuit patterns or trace routing limitations exist, by using plated thru-hole technology to utilize both sides of the PCB.
- Plating options such as gold, tin-lead, and nickel.
- Can be used in extreme environments, and high-reliability/high-vibration environments.
