Thermal Switches
Proven, power-free temperature control for critical aerospace and defense applications
Acron Aviation’s Thermal Switches provide precise, self-powered temperature control for the world’s most demanding aerospace, defense, and industrial systems. Built to MIL-PRF-24236 and S-311-641 standards, each switch is individually tested and qualified for consistent, long-life performance across extreme environments.
Built for demanding environments
From flight decks and propulsion systems to spacecraft and military vehicles, the industry demands high-quality thermal control solutions for mission-critical systems. Acron Aviation’s thermal switches are simple, rugged, and reliable, engineered to perform without external power.
Each switch is a snap-acting device that opens or closes an electrical circuit in response to temperature changes. Designed for flexibility, our switches support a wide operating range from -110°F to +700°F, making them suitable for both extreme cold and high-temperature applications.
