を提供するものである。When such a keyboard switch is used for a long period of time, the switch sheet member flexes and eventually the upper and lower contacts contact each other constantly and lose the switch function, or even if they do not contact, the operating pressure or operating pressure decreases. It becomes difficult to maintain the initial state as a decreasing LJ switch. □ The present invention solves the above problems and provides a keyboard switch that can ensure stable operating pressure or operating pressure over a long period of time.
