Here we introduce to you about how membrane switches are made.
The circuit layer of waterproof membrane switch adopts polyester film (PET) with good electrical performance as the carrier of switch circuit graphics.
This layer is also divided into hand shrapnel and upper and lower circuits. Due to the influence of the properties of polyester film, the capacitive membrane switch has good insulation, heat resistance, bending resistance and high resilience.
The graphics of the switch circuit, including the on-line and outgoing lines of the switch, are printed with low resistance and conductive coating cured at low temperature.
