Plastic Name Plate with Embossed or Flat keys
The material is Polycarbonate (PC) or Polyester (PET). If the material used is PET, the embossed keys can have a tactile or non-tactile effect depending on the shape of the keys. This keypad can also be used indoor or outdoor equipment and can last over 500 thousand presses without tearing.
PC cost is lower than PET but it is suggested to use in equipment that is for indoor use and less presses since the key surface could be broken after 50 thousand presses. The embossed keys using this material also don’t have any tactile feeling due to the characteristic of PC material.
Conductive carbon or silver paste could be printed on the back side of embossed or flat key to become a functional button. This foil is used together with our membrane switches using silver printed circuit or any mechanical switches.
