Abstract

A device to detect an iron'"'"'s position includes a constant voltage regulator, a frequency pick up unit, an integrated circuitry chip, a sensor unit and a control unit. The frequency pick up unit is connected to the constant voltage regulator. The frequency pick up unit includes a resistor connected to a capacitor to retrieve the frequency signal of the input voltage. The integrated circuitry chip includes a frequency producer connected with a frequency identifier. The sensor unit includes a metal ball disposed on an arc track to control the signal input of the frequency pick up unit. The control unit is connected to the frequency identifier. The frequency identifier triggers a signal to change the working mode of a transistor of the control unit.
