RACON 8
RACON short-travel keyswitches
General data
RACON short-travel keyswitches offer an extremely high switching reliability while needing very little space. They can be
arranged as single keys, in rows or key blocks.
When arranged under an overlay, RACON keyswitches should be combined with plungers.
The features at a glance:
• Suitable for the most common soldering methods
- Wave soldering bath for print versions
- Reflow soldering (SMD)
- Manual soldering
• SMD version suitable for processing with an automatic SMD assembly machine
