Capacitive Touch Membrane Switch
The capacitive touch membrane switches are classified into two types according to the circuit type: one is ITO conductive film etched; the other is printed transparent conductive ink (PEDOT).
Higher light transmittance for the type of ITO conductive film etched circuit, and its cost is also higher. The type of transparent conductive ink (PEDOT) printed circuit costs are relatively low and lower light transmittance, it can meet the vast majority of application requirements.
Nowadays, the capacitive touch membrane switches applied in home appliance industry and the automotive electronics industry are all of the type of transparent conductive ink (PEDOT) printed circuit.
