tactile keypad flexible FPC Membrane Switch embossed button and
LEDs
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.
For the Rigid circuit membrane switches, the circuit is rigid
printed circuit board. The material of rigid PCB is usually FR4 and
Copper. By this type of membrane switch, the connector usually is
the SMD connector(sometimes also can be straight through
connector). For some application which need very stiff capability,
then use PCB circuit membrane switch.
