Claims

[Claims for Utility Model Registration] A box-shaped base that is open on one side and closed on the other side, one end of which is exposed at the inner bottom of the closed side of the base, and the other end of which protrudes outward from the base. a plurality of sets of lead frames, each pair of which is arranged as a pair; a thin disc-shaped reversing spring for switching operation that electrically turns on or off the lead frame; and a reversing spring located directly above the reversing spring. a flat flexible pressing member disposed so as to be able to come into contact with the reversing spring and having an electrically insulating property for pressing the reversal spring; and an opening formed to expose the flexible pressing member. A mechanical key switch comprising: a cover that closes the opening side of the base while clamping and fixing a peripheral edge of the flexible pressing member at an appropriate location with the opening side peripheral edge of the base.
