The 3153 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. The low silhouette and compact design often make it especially well-suited for applications that require miniaturization. Acceptance testing is performed in accordance with MIL-S-24236, Table III.
