 |
| characteristics |
|
Several options are
available. |
|
| 1. |
|
KTP-type: The KTP-type, one of the basic Rubber-Contacts
in the series, characteristics a molded key top with letters and icons printed
on it. The KTP-type series incorporates spring and button operational
functions, as well as switching, into a single rubber sheet. |
| 2. |
PB-type: The PB-type Rubber Contact combines a silicone
body, with a plastic top. |
| 3. |
IM-type: The IM-type Rubber Contact combines plastic such
as polycarbonate, PBT, PA66 with silicone rubber. Flexible design is
available by this type. |

 Under study.
 Production
is not possible.
| *1 |
|
The Rubber-Contact cannot be manufactured
for some key top profiles and under other conditions. |
| *2 |
Only the uppermost surface of the
key top can be processed. However, the total surface can be processed
for semi-hard (SH) products. |
| *3 |
|
We can manufacture this Rubber-Contact
by using PB-U type material for the key top. |
