A membrane switch is an electrical switch for turning a circuit on and off. It differs from a mechanical switch. Membrane switch is very thin and soft. The touch surface material usually is PET or PC. The circuit can be PET, FPC or even PCB. Membrane switches are user-equipment interface utilities that allow for the communication of commands from users to electronic devices. Teingesch mainly provides membrane switches, capacitive switches, membrane keypads, rubber keypad switches, PCB/FPC membrane switches, graphic overlays, waterproof membrane switches, UV-resistant membrane switches, touch display modules etc. to the customers from all of the world. We also can provide PCBA design, SMT service, Single-chip development and contract manufacturing services for all our customers.

The circuit of membrane switches can be flex and rigid. It depends on the customer end application and also related to the cost budget and other considerations. For example, life, resistance, connection type on the mainboard, etc. Usually if the membrane switches need assembled many LEDs, then we suggest to use FPC circuit, it can get more stable LED soldering quality. For the normal application the PET circuit is enough, which is more economical. In addition if the conductor pitch is 0.5mm, although we also can print it, but we still suggest to use FPC circuit. Because of that 0.5mm pitch is too small and it is easy to occur the short circuit problem.

Details of Flex & Rigid Membrane Switches: The circuit of membrane switches can be flex and rigid. It depends on the customer end application and also related to the cost budget and other considerations. For example, life, resistance, connection type on the mainboard, etc. For the Rigid circuit membrane switches, the circuit is rigid printed circuit board. The material of rigid PCB is usually FR4 and Copper. By this type of membrane switch, the connector usually is the SMD connector (sometimes also can be straight through connector). For some application which need very stiff capability, then use PCB circuit membrane switch. For the flex circuit membrane switches, there are two types. They are silver printed PET circuit and copper etched FPC circuit. Usually if the membrane switches need assembled many LEDs, then we suggest to use FPC circuit, it can get more stable LED soldering quality. For the normal application the PET circuit is enough, which is more economical.
