SERIES 3600/3601 TO-5 THERMAL SWITCHES Typical Applications: Printed Circuit Boards Logic Level or Dry Circuit Applications The Series 3600/3601 of TO-5 Switches are single- pole, single-throw, bimetal snap-action switches available to open or close on temperature rise. These quality-engineered devices are specifically designed for mounting on printed circuit boards to protect against hazardous temperatures associated with the thermal density of compo- nents on backplanes, flexible circuitry and sophisticated time-based circuits. The Series 3600/3601 is packaged in a standard JEDEC TO-5 transistor housing with .75" length (19mm), .018" (457mm) diameter leads. These devices represent the first hermetically sealed switches in a TO-5 package that is wave solder- able for increased labor efficiency. To insure that a safe combination of thermostat and application is achieved, the purchaser must determine product suitability for their individual requirements. 14 Bimetal Disc Insulator a a Housing Contacts $F-4 SS Contact Arms Resistance +f Weld i Base Glass Header + Case Ground Lead Series 3600/3601 LIFE CYCLES 28VDC/AC 5VDC/AC 10,000 1.0A 5.0mA mA: milliAmps A: Amps Consult Elmwood Sensors for additional ratings.
