Silicon rubber switches are most suitable for the fast entry applications, these can be made in variety of customised shapes and colours and hence are different than the other switches. The Silicon layers are sandwiched with the Non -Tactile keyboard in such a way that the keyboard is sealed from the dust and liquid attacks. Silicon rubber keyboards can be sandwiched with regular Tactile or Non - Tactile Membrane Keyboard so that one can avoid the heavy tool cost for the injection moulded enclosure to mount these keyboards.
These can be illuminated to view in dark and hence are best suitable for Medical equipments and Military applications.
Silicon keyboards are used in many applications, for example in communication systems, consumer products etc. In comparison to other keyboard technologies the silicon keyboards do have an excellent price to performance ratio. Unlimited designs are possible. Shape & colours of the keytops can be designed at your wish. Silicon keyboards are make of high flexible & toxin free silicon. Pressure & appropriate temperature will produce the right keyboard, a special tooling is required for every different design. The final contact is made by using a conductive silver dot which shorts the electrode on the PCB. Silk screen printing method is generally used for the printing on the keys, if required it can be coated with epoxy to improve the resistance against abrasion. |
