This family of switches is the basis for many applications, combining small size with robust electrical characteristics packaged for severe environments with flexible mountings.
One of the greatest strengths of this switch is the push-to-open contact design. This means that the force of the flat spring is providing consistent closing force compared to other designs which use the bimetal disc to maintain closure of contacts.
The available force for closing contacts using the disc is diminished as the snap-point is approached, increasing susceptibility to vibration and shock.
The 500 Series switches are manufactured in a controlled environment with temperature set points tested by a computer to assure accuracy and uniformity. The discs are 100 percent tested prior to assembly – no sample testing allowed.
• The 570 Series supports applications to 400°F upper ambient
• The 550 Series supports applications to 550°F upper ambient
• The devices meet or exceed all conditions of MIL-PRF-24236/1
• Higher temperatures are available as customs
Yes, we retrofit legacy systems (e.g., GE Frame 5, Siemens V94.2) with modern digital controllers, typically completing hardware integration within 4-8 weeks. Software migration requires additional validation time.
We recommend annual performance testing under ISO 3977-2 standards. Critical applications (e.g., offshore platforms) may require semi-annual tests with emissions compliance checks.
All rad-hard devices (e.g., FPGA, ADC) are QML Class V certified under MIL-PRF-38535 and tested to MIL-STD-883 Method 1019 for SEU tolerance. Full qualification reports are available upon request.
Our ASICs and power management ICs operate across -55°C to +175°C ambient temperatures, with derating curves provided in military temperature range (MTR) datasheets.
Our PMA parts (e.g., actuators, sensors) hold FAA/EASA Form 1 certification and match OEM form/fit/function. Installation requires SB/MB documentation per FAA AC 23.1529.
All NAS/MS fasteners include full DNA traceability: melt source (AMS 2301), heat/lot numbers, and AS9100-compliant MTRs with ultrasonic test reports.
AOG orders ship within 4 hours for stocked items (FAA-PMA, EASA Part 21G). Non-stock critical parts trigger priority manufacturing with 72-hour max turnaround.
