Keyboard structure
A keyboard structure includes an elastomer, a flexible conductor and a conductive circuit board from top to bottom. The conductive circuit board is respectively provided with a circuit anode and a circuit cathode, the flexible conductor includes a flexible body and a conductive layer arranged on the flexible body. When pressing the elastomer, the circuit is switched on if the conductive layer on the flexible conductor is in contact with the circuit anode and the circuit cathode on the conductive circuit board. When loosening the elastomer, the circuit is switched off if the conductive layer on the flexible conductor is separated from the circuit anode and the circuit cathode on the conductive circuit board.
