  • Sealed Enclosure - IP-54 rating protects internal components from dust ingress and moisture, extending switch life in varied environments.

  • Low Actuation Force - Requires under 100 gf to actuate, reducing mechanical load on linkage and improving tactile response.

  • Compact Footprint - Fits standard 0.375 × 0.250 in panel cutouts, allowing installation in tight control panels and avionics racks.


  • Position sensing for cockpit levers and circuit-breaker panels.

  • Interlock detection on avionics bay doors and access panels.

  • Control-signal switching in cabin lighting and attendant call systems.

  • Input detection for environmental-control valves and airflow flaps.


  • How is the switch sealed against contamination?

The molded polymer housing and internal gaskets provide IP-54 protection, blocking dust and moderate moisture.

  • How many cycles can the NSA933635-09 endure?

It is rated for over 1 million mechanical cycles, minimizing replacement frequency in high-usage locations.

  • Is this switch life-limited?

No, there is no specified life limit. However, it should be inspected for actuation force and contact wear during routine maintenance.
