Advantages of PCB Based Membrane Switch :

• • Durable & high life expectancy compare with PFC membrane switch.
• • Lower electrical resistance/higher conductivity.
• • Soldering of many component possible for this type of keypad.
• • Ideal for smaller designs where dense circuit patterns or trace routing limitations exist, by using plated thru-hole technology to utilize both sides of the PCB.
• • Can be used in extreme environments, and high-reliability/high-vibration environments.
• • Dustproof & Prevention from ingress of moisture & solvent.
• • Flexibility for using Connector.
