Thermostats
3500 Series
Military. Hermetically sealed. Tight tolerances & differentials. SPST contacts. Mounting brackets, terminals.
Overview
The 3500 Series consists of a single pole, single throw switch activated by a snap action bimetal disc. Temperature calibrations are pre-set at the factory, and each unit is 100% thermally and mechanically inspected. It is available to open or close on temperature rise. The case is laser welded to form a hermetically sealed steel housing, with a glass-to-metal seal at the terminal junction. It meets or exceeds the requirements of MIL-S- 24236 and is designed specifically for military and commercial aircraft applications. It is not QPL listed (see 3MS1).
