摘要： 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.

摘要： A balancing structure for a long key of a keyboard includes a balancing rod and a pair of clamping hooks arranged on a bottom plate of the keyboard. The balancing rod includes a cross rod matched with a keycap of the key and two sliding rods extending from two end parts of the cross rod and matched with the pair of clamping hooks respectively. During the keycap pressing or spring-back process, each of the two sliding rods slides on a clamping port edge on at least one side of the corresponding clamping hook along with the rotation of the cross rod, and the moving trajectory of the contact point of each sliding rod and the corresponding port edge is an arc in the sliding process.
