One Key FPC Membrane Switch
Compared with traditional membrane switches by using the PET silver paste printed flex as the circuit layer, the one key FPC membrane switch is made from Polyimide copper etched FPC circuits. Copper flex traces are more durable and stable, which are resistant to high temperatures up to 280°C, the circuit has high precision, output spacing of 0.5mm or others, low electrical resistance value, high conductivity, stable and reliable performance, and one key FPC membrane switch service life longer than normally membrane switch, ability to solder many kinds of components into the switch design.
