Overview

The 3200 Series is a single-pole, single-throw switch activated by a snap-action bimetal disc. It is manufactured and tested to meet or exceed critical military and aerospace specifications for spaceflight use, including temperature stability, shock, vibration and cleanliness. The case is laser welded to form a hermetically-sealed steel housing, with a glass-to-metal seal at the terminal junction. Temperature calibrations are pre-set at the factory and each unit is thermally and mechanically inspected. It is available to open or close on temperature rise. The 3200EM (Engineering Model) version is produced using the same components as the 3200, but is not subjected to the rigors of extensive flight testing. It is specifically designed for ground and experimental testing.
