Abstract: A dustproof and droplet-proof keyswitch is provided. The keyswitch includes a base plate with at least one stage formed thereon, each stage having a step portion formed at a top part; an elastic member arranged on the step portion; a key cap mounted on the elastic member and having a plunger inserting into the stage. The plunger has an elastic plate clamped between a pair of grooves and having a hook on a lower end thereof; the hook having a beveled lower end latched with the stage when the key cap is released. The stage has at least one projecting rib on an inner side thereof corresponding to at least one notch on the plunger to provide a clamping effect. Therefore, the keyswitch can be used under severe conditions such as in a dusty environment or when the keyboard has spilled on it a liquid such as tea or coffee.

Abstract: An improved keyswitch includes a stage having a mounting hole and a keycap having a plunger on a bottom thereof. The plunger is movably arranged within the mounting hole. The keyswitch is characterized in that one of the keycap and the stage is provided with at least one guiding rib, while the other of the keycap and the stage is provided with at least one dent corresponding to the guiding rib. The guiding rib is fit within the dent and the dent and guiding rib have multiple point contacts to restrict movement of the keycap with respect to the stage.

Abstract: An improved keyswitch comprises a stage having a mounting hole and a keycap having a plunger on bottom thereof. The plunger is movably arranged within the plunger. At least one guiding rib is provided within the stage or on lateral side of the keycap; and at least one groove corresponding to the guiding rib is provided on lateral side of the keycap or within the stage, the guiding rib fit within the groove such that the keycap is movable upward and downward within the mounting hole without shaking. The keycap is in contact with the stage on lateral side thereof, the friction therebetween is reduced.
