Half Inch Snap Disc Thermostat

The encapsulated half inch snap disc thermostat  snap discs are used whenever a moisture and dust proof enclosure is required for safe, sensitive and reliable operation.

An optional polypropylene boot enclosure, filled with epoxy resin, covers the thermostat. The bimetal disc control element is in close proximity to the sensor cap to provide rapid response to temperature changes. Since the bimetal disc used in the Half inch snap disc thermostats are thermally and electrically insulated from the current carrying parts of the thermostat, the disc reacts only to the temperature of the controlled device or medium surrounding the disc.

Instantaneous, positive action of the disc prolongs thermostat life by minimizing arcing and eliminates chattering, false cycling and electrical interference with radio and television reception. Long life is assured with wiping contacts.
