Keypads use special moulding technology
9 August 2006, Switches, Relays & Keypads
With the advent of more customised designs for electronic devices such as cellphones, remote security, access control and input units, etc, Technological Rubber developed a 'rubber to plastic' moulding technology.
The base layer is still silicone rubber, usually translucent for backlighting. The top layer is plastic, which gives a 'hard' feel whilst the silicone layer allows the different activating force, travel and tactile function. The finish on the key tops 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 is moulded over the silicone, providing complete protection to the silk screen. Laser 'nightlight' engraving can also be used for the silk screen. |
