PCB (Printed Circuit Board) Switch ——The circuit layer of the membrane switch adopts PCB material.
Advantages: Low resistance; High-precision circuits; It can be directly welded with some components of the circuits on the back of the PCB switch.
Disadvantages:It can be more than a little inconvient when assemblying the whole machine, compared with FPC switch, because it needs to be soldered the connector and threaded the lead with flat cable.
