PCB membrane switch

PCB membrane switch means that the pattern and circuit of the switch are made on the common printed circuit copper clad board.

The characteristic of PCB membrane switch is that the material is easy to use, the process is stable, the resistance is low, and some components in the circuit can be directly welded on the back of the PCB. In the case of a small area, the hard liner layer can be omitted. PCB can be made with a thickness of 0.5mm-3.0mm.

PCB membrane switches generally use metal guides as conductive labyrinth contacts, so they have a better feel. The disadvantage is that it is not as convenient as the flexible membrane switch to install and connect in the whole machine, and it is often necessary to weld the connector and lead the lead through the flat cable. In addition to the buzzer signal and LED indication, the information feedback of the rigid membrane switch can generally use metal handle shrapnel.
