Notes and Usage Recommendations
- Intended for signal-level switching; avoid direct power switching.
- For sealed models, use recommended gasket compression and enclosure tolerances to maintain IP rating.
- Validate acoustic performance in final enclosure, as housing and keycap materials influence sound.
