Methods, systems, apparatuses, and computer program products are provided for a user input device, such as a game controller, that includes a finger-pressable (tactile) switch. The switch is adjustable to change the amount of force used to actuate the switch. In an example implementation, a tactile switch comprises a housing, a button interposer, a dome switch, and an adjustment mechanism. A user or other entity may press the button interposer. The dome switch is contained in the housing, and is actuated by the button interposer being pressed. The adjustment mechanism is contained at least partially in the housing, and is configured to enable an amount of force used to press the button interposer to actuate the dome switch to be adjusted.

A keyswitch structure includes a base having a positioning means, an cover combined with the base, a plunger with an cam portion movably coupling with the cover relative to the base, a restoring unit disposed between the base and the plunger to provide a restoring force to enable the plunger to move along a direction away from the base, a tactile feedback member having a positioning portion positioned by the positioning means and an extending arm extending across a moving path of the cam portion, and an adjusting unit being movable to drive the positioning portion to shift, so that the tactile feedback member has a first deformation or a second deformation, and a pressing force required for the cam portion to pass the extending arm when the plunger moves toward the base is changed.

A keyboard includes a plurality of keyswitch structures and an adjusting plate movably disposed under the keyswitch structures. Each of the keyswitch structures includes a tactile feedback member. The adjusting plate includes a plate body and a plurality of adjusting bars protruding from the plate body toward the keyswitch structures and respectively corresponding to the tactile feedback members of the keyswitch structures. When the adjusting plate moves relative to the keyswitch structures, the adjusting bars drive the tactile feedback members to change tactile feedback of the keyswitch structures.

A button module is provided. The button module comprises a base, a pressing part, and an elastic part. The pressing part includes a fixed end and a free end. The fixed end is pivotally connected to the base in a first axial direction. The elastic part is disposed on a side of the pressing part facing the base. The elastic part includes a first damping portion and a second damping portion selectively pressing against the base, where a hardness of the first damping portion is different from a hardness of the second damping portion.

A button switch connected to a cap and includes a base having a pillar, a flexible acoustic member having fixing and flexible rods, a sleeve, an upward-force-applying member abutting against the sleeve and the base, a resilient arm, and a cover disposed on the base. The sleeve rotatably jackets the pillar, passes through the cover to be connected to the cap, and has first and second convex portions, first and second concave portions, and a protruding edge located between the second convex portion and the second concave portion. The resilient arm selectively abuts against a first or second position on the first convex portion. When the resilient arm abuts against the first position and the protruding edge is located above the flexible rod, the flexible rod crosses the protruding edge and then collides with the cover to make a sound when the sleeve receives an external force to move downward.

A keyswitch includes a cap, internal and external sleeves, a resilient arm, a base having a pillar, and an elastic member abutting against the internal sleeve and the base. The internal sleeve jackets the pillar, abuts against the cap and has a first outer annular surface with a transverse slot. The external sleeve jackets the internal sleeve and has a protruding block movably inserted into the transverse slot for guiding the external sleeve to rotate and a second outer annular surface having concave and convex portions and an arc-shaped bar. When the resilient arm abuts against a second position on the convex portion and the cap presses the external sleeve, the resilient arm crosses the arc-shaped bar. When the resilient arm abuts against a first position on the convex portion and the cap presses the external sleeve, the resilient arm does not need to cross the arc-shaped bar.

A keyswitch with adjustable tactile feedback is adjusted by an adjusting method. The keyswitch includes a baseplate, an upper housing, an upper bushing component, a lower bushing component, a keycap and a recovering component. The baseplate has an electrode module, the upper housing is disposed on the baseplate, the upper bushing component is movably disposed on the upper housing, the lower bushing component is movably located between the baseplate and the upper housing, and the keycap is connected to a connecting portion of the upper bushing component. The lower bushing component can rotate relative to the baseplate to switch between a first position and a second position. The lower bushing component has a first lateral surface and a second lateral surface with different shapes. The recovering component is disposed between the baseplate and the lower bushing component to upwardly push the lower bushing component.
