Thermal switch for electric fan heater AMT-A
AMT-A and AMT-C thermal switch’s Principle and structure
Quickly respond to the variation of temperature, and has the
function of automatic reset. No current flows through bimetal so
the influence of self-heating effect is avoided and it leads to a
long service life with little change in temperature. Environmental
friendly high-power sliver contact is adopted, being accord with
the demands of safety approval for export.
AMT-A and AMT-C thermal switch’s application
1. It is applicable to the thermal radiation control on various
electric heating appliance including electric Hair Dryer, Electric
Fan Heaters, Popcorn Machines, Electric Ovens, Dish Dryers,
Electric heaters, dehumidifiers, stewpots etc.
2. Never touch active piece or temperature sensor during the
installment and utilization fo thermal protectors, or it will lead
to the failure of protectors because of inaccurate temperature and
loose contact.
