The RF 19 silver tactile switches have a 19 x 19 mm edge length, reliable silver contacts, and a noticeable click. They are used in flat data entry keyboards under overlays or under keycaps, such as RAFI RK 90 keycaps.
Flat data entry keyboards with RF 19 elements should be constructed in a 23 mm grid. With this grid, glue strips remain between the individual keys on the front panel. The overlay, which we recommend embossing above the key switches, can be glued onto these strips of glue.
