The hold down 1824 is used to hold down the key assembly electrical connector portion to allow communication between the key assembly electrical connector portion and the connector 132.

At the same time, drive assembly 190 drives the crimp assembly forward, moving to the point where first crimp portion 180, second crimp portion 181, and third crimp portion 182 of the crimp assembly correspond with portions of the key assembly. The drive assembly 190 drives the press-fit assembly to press downwards, the first signal transfer block 131 is in contact with the metal ring at the back of the circuit board part of the key assembly to be conducted, the electrical connector part of the key assembly is in contact with the connector 132 to be conducted, meanwhile, the lifting assembly drives the lifting plate 170 to move upwards in the vertical direction, so that the head end of the conductive piece 130 is connected with the key part of the key assembly to be conducted, and signal detection is started. After the detection is finished, the lifting assembly drives the lifting plate 170 to move downwards, the lifting plate 170 returns to the initial position, and the conductive piece 130 is separated from the key part of the key assembly; at the same time, the driving assembly 190 drives the press-fit assembly to rise, the first signal transfer block 131 is separated from the metal ring on the back of the circuit board portion of the key assembly, and the electrical connector portion of the key assembly is separated from the connector 132.
