APEM 4 Key Illuminated Membrane Keypad

Self-adhesive matrix membrane keypads

A unique feature of these keypads is the 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´4 and the 4´3 keypads, is formed by inserting two sheets, chosen from a set of 4 supplied with each keypad, into the two pockets of the keypad
4´1 keypad, requires one sheet (from the two supplied) to be inserted. Alternatively other suitable paper or polycarbonate legend sheets may be used
After inserting the legends, the self-adhesive keypad can be affixed on to any suitable clean flat surface
Flexible tail of the keypad may be terminated by means of a female connector to mate with PCB headers connectors e.g. see stock no 467-576
