And the coil 2 and the metal piece 33 can have an open circuit at the corresponding position in the vertical projection area of the buried wire layer 44, when the automatic reset key 31 is pressed to the preset position, one end of the metal piece 33 can be connected with one end of the open circuit of the coil 2, the other end of the metal piece 33 can be connected with the other end of the open circuit of the coil 2, the coil 2 is communicated, and the chip 1 recovers the function of non-contact reading and writing. When the user does not need to use the chip card, the automatic reset key 31 is released, the metal piece 33 is separated from the contact with the coil 2 along with the reset of the automatic reset key 31, the coil 2 is disconnected, and the chip 1 loses the function of non-contact reading and writing.
In addition to providing the foregoing example of the switch 3, the present embodiment also provides an example of a coil 2, a band winding open circuit exists at a position corresponding to the position of the automatic reset key 31 in the vertical projection area of the buried wire layer 44 in the coil 2, one end of the band winding open circuit tilts towards a direction close to the automatic reset key 31, the other end of the band winding open circuit is disposed on the buried wire layer 44, a vertical projection of the band winding open circuit on the buried wire layer 44 is intersected with the other end of the band winding open circuit, and the automatic reset key 31 can drive one end of the band winding open circuit and the other end of the band winding open circuit to contact when being stressed and in a pressed state, so that the coil 2 is communicated.
In this embodiment, a band winding open circuit (refer back to fig. 1) may be disposed in the coil 2 at a position corresponding to the automatic reset button 31 in the vertical projection area of the buried layer 44, one end of the band winding open circuit may be tilted, the other end may be disposed on the buried layer 44, and the vertical projection of the tilted end of the band winding open circuit on the buried layer 44 may intersect with the other end of the band winding open circuit disposed on the buried layer 44.

The sound generated by the spring leaf can not only remind the user of the state of the current automatic reset key 31, but also preliminarily judge the fault problem when the chip card has a fault, for example, if the user hears the sound but the chip card cannot be used normally, the problem may occur in the chip 1 or the coil 2, and if the user does not hear the sound when repeatedly pressing, the problem may occur in the switch 3.
