Flat Membrane Switch Panel

How to see the quality of the switch panel?

First, a good quality switch socket is heavier than a poor switch socket. (You can use the poor and good hand to try) Again: look at the hardness of the face of the switch socket, take the switch case and hold both ends of the case gently to twist, see his hardness is not strong and the difference of the switch shell phase ratio. Secondly: the density of the copper piece of the socket, a socket and a plug, the plug is inserted into the socket, if it is lightly dialed, the density is not so good. The density of the copper piece is loose, because the plug is plugged in and the working copper piece is charged. The density is tight and the spark is easy to produce. Finally: look at the thickness of the switch copper plate of the business display products

Then there is the appearance of the switch you like.
