Keypads cleverly customised

21 March 2007 Switches, Relays & Keypads

With the advent of more customised designs for electronic devices, for example: cellphones, remote security and access control and input units etc, Technological Rubber developed its 'rubber to plastic' moulding technology. The base layer is still silicone rubber, usually translucent for back-lighting, while the top layer is plastic. The top plastic layer gives a 'hard' feel whilst the silicone layer allows for the different activating force, travel and tactile function. The finish on the keytops can be silvered, chromed and/or coloured.

One major advantage is that the silkscreen can be applied to the top surface of the silicone layer and then a transparent plastic layer moulded over the silicone. This gives complete protection to the silkscreen. Laser 'nightlight' engraving can also be used for the silkscreen.
