The 3156 Series is a single-pole, single-throw switch activated by a snap-action bimetal disc. It has WE-1 gold alloy cross point contacts for use in potential low voltage applications The case is laser welded to form a hermetically-sealed steel housing, with glass-to-metal seal at the terminal junction. Its low silhouette and compact design allows use in most applications that require miniaturization. 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. A variety of mounting brackets and terminals is available.
