Open Frame Bimetal Temperature Thermal Switch ST-12 AMT Thermostat For Hair Dryer
Description Of The Thermal Switch ST-12 AMT Thermostat For Hair Dryer
The AMT Series thermostat available from AMPFORT offers an open frame design and provides a safer and more reliable protection on circuits.The PTC component and contact circuit form a parallel circuit. With the heating up of temperature, the contact circuit is off and current flows through PTC component to form a loop.The temperature of the PTC component increases rapidly, and being higher than the rated reset temperature, it keeps the circuit in the off state. When the main power is removed, the temperature decreases to the reset temperature of bimetallic strip, the strip recovers rapidly and contact closes.
Features of Structure Of The Thermal Switch ST-12 AMT Thermostat For Hair Dryer
1. Quickly respond to the variation of temperature, and has the function of automatic reset.
2. No current flows through bimetallic strip so the influence of self-heating effect is avoided and it leads to a long service life with little change in temperature.
3. Environmental friendly high-power silver contact is adopted, being accord with the demands of safety approval for export.
4. Applies imported environmental friendly material which is approved by SGS test.
