RS – Self-adhesive matrix membrane keypads and developer’s kit (Apem - AC3875)Aug 13 2012 - Design & Manufacture [More Design & Manufacture Articles]
Apem’s self-adhesive matrix membrane keypads and developer’s kit are now available from RS Components. A novel feature of the keypads is an insertable polycarbonate sheet carrying standard printed legends on one side - the other side can be user marked (written, typed or transferred symbols) to provide complete legend customisation and the removal of any limitation on keypad orientation.
The legend for 4 x 4 and the 4 x 3 keypads, is formed by inserting two sheets, chosen from a set of four supplied with each keypad, into the two pockets of the keypad.
The 4 x 1 keypad, requires one sheet (from the two supplied) to be inserted. Alternatively other suitable paper or polycarbonate legend sheets may be used.
By punching holes in the legend sheet it is possible to provide individual key indication (via LED) and by use of a translucent legend sheet overall back illumination may be achieved After inserting the legends, the self-adhesive keypad can be affixed on to any suitable clean flat surface. The flexible tail of the keypad may be terminated by means of a female connector to mate with PCB headers / connectors.
Each keypad has a black polycarbonate top layer with silver embossing and printing. The double-sided silver legend sheet has black legend printed on one side, with the other side blank.More news from RS Components
