Claims (1)

[Claims for Utility Model Registration] (1) A plurality of fixed electrodes fixed to the inner bottom surface of a base with an open top, and a plurality of fixed electrodes located above and facing the plurality of fixed electrodes inside the base. a movable electrode that is positioned as shown in FIG.
an opening/closing button whose upper end protrudes above the opening of the base and whose lower end contacts the movable electrode inside the base and causes the movable electrode to elastically deform when pressed from above; A key switch comprising a cover that is fixed and holds the opening/closing button in a predetermined position, and a plurality of elastic engagement means are provided on the peripheral edge of the cover, and a plurality of elastic engagement means are provided on the side surface of the base. By providing a locking portion and locking the engaging means of the cover to the locking portion of the case, the cover always holds the opening/closing button in a predetermined position due to the elasticity of the engaging means. A key switch that is characterized by the following: (2) Utility Model Registration In the key switch according to claim 1, the engaging means of the cover are provided at mutually corresponding positions on the peripheral edge of the cover and protrude downward substantially perpendicularly to the cover. The base comprises two elastic arms each having an engaging window near the tip thereof, and the locking portion of the base is comprised of a protrusion that locks the locking window of the arm. key switch. (3) In the key switch as set forth in claim 2 of the utility model registration claim, the engagement arm of the cover has a curved portion at the base thereof connected to the peripheral edge of the cover to enhance the elasticity of the arm. A key switch characterized by:
