Custom building keypads with COSMOS & MICRO-COSMOS KEYPADS

Customers can build their own keypads and keyboards using MICRO-COSMOS and COSMOS modular key switches. By combining the switch elements of choice with other components such as LEDs, termination hardware, semiconductors, and passive components on your own printed circuit board, a complete drop-in custom keypad can be constructed. The resulting assembly offers flexibilty, graphic appearance, and front panel sealing found in membrane systems, combined with the rugged dependability of high quality precision tactile key switches. LED- equipped switch modules provide bright, even illumination. The illustrations below show some possible mounting arrangements. See the MICRO-COSMOS and COSMOS sections in this catalog for technical specifications. Consider custom assembling your own devices when you need a special keypad or switching panel.

  1. Front panel overlay
    Manufactured to specifications in polycarbonate or polyester with silk screening on back. Thickness: 0.175 to 0.250mm. With or without embossing.
  2. Device front panel
    Front panel holes to accommodate module and other components (LED, switch, etc.). Maximum thickness: 4mm for MICRO-COSMOS, 3.5 mm for COSMOS.
  3. Protective Button
  4. Key switch module - eithor illuminated or non-illuminated
  5. Spacer
  6. PCB
  7. Protective lens
For better flexibility, it is recommended that modules be countersunk on top surface.
