Methods, systems, apparatuses, and computer program products are provided for a user input device, such as a game controller. The user input device includes a finger depressible trigger button, a trigger travel path adjustment assembly that resides in an internal cavity of a housing of the user input device, and a finger switch configured to be switched between a plurality of selectable positions in real-time (e.g., during game play). A first selectable position of the finger switch enables the trigger button to be depressed a first distance. A second selectable position of the finger switch enables the trigger button to be depressed a second distance that is greater than the first distance.

An input device having an overlapping key structure includes a plurality of keys, each of the plurality of keys configured to actuate a respective key switch in response to an applied mechanical force; and a key support frame, where each of the plurality of keys includes a spring arm portion coupled to the key support frame at a first end of the each of the plurality of keys such that the each of the plurality of keys deflects through a range of motion in response to the applied mechanical force, and each of the plurality of keys overlaps with another one of the plurality of keys such that each of the plurality of keys is included in an envelope of a two-dimensional cross section of the range of motion of another one of the plurality of keys when viewed from a direction perpendicular to the two-dimensional cross section.

A button structure and a terminal using the same are provided. The button structure includes a connecting element, a press element, and at least one elastic element connected to the connecting element and the press element. The elastic element is configured to provide a restoring force after the press element is pressed toward the connecting element. The connecting element is provided with an instruction transmission port and at least one of a current transmission port and a data transmission port. The press element is provided with an instruction triggering port and at least one of a current transmission pin and a data transmission pin. The current transmission pin is electrically connected to the current transmission port to output or input current. The data transmission pin is electrically connected to the data transmission port to output or input data.

A switch device includes at least one spring, a sliding body and a circuit board. The at least one spring is configured to generate a switch signal corresponding to an inductance of the at least one spring, and includes a first spring portion and a second spring portion arranged along a first direction. The inductance is associated with a first interval between the first spring portion and the second spring portion. The sliding body is configured to move along the first direction to change the first interval. The circuit board is configured to receive the switch signal. The at least one spring is located between the sliding body and the circuit board.

A keyswitch structure includes a base, a keycap, a lift mechanism and a light-emitting part. The lift mechanism includes a first support, a second support, and a spring structure. The first support and the second support are connected to and between the base and the keycap, so that the keycap can move relative to the base in a vertical direction. The spring structure is a single structural part and is connected to the first support and the second support and drives the first support and the second support to lift the keycap in the vertical direction. The lift mechanism as a whole defines a central space that extends through the whole lift mechanism in the vertical direction. The spring structure does not enter the central space. The light-emitting part is disposed on the base corresponding to the central zone, and emits light to illuminate the keycap.

A keyboard has a keyswitch capable of showing its movement depth. The keyswitch includes a substrate, a lifting unit, a multistage positioning component and a keycap. The lifting unit is disposed on the substrate. The multistage positioning component is disposed on the substrate and has a plurality of first actuating portions. The keycap is connected with the lifting unit and adjacent by the multistage positioning component. The keycap has a second actuating portion. The keycap is moved relative to the substrate via the lifting unit, and the second actuating portion can contact against one of the plurality of first actuating portions to generate a feedback signal.

A high-voltage earthing switch is disclosed. A static contact of the earthing switch is connected with the first end of a conductive copper busbar. The second end of the conductive copper busbar is connected with a transformer. The conductive copper busbar includes a first segment and a second segment connected with the first segment. The first segment is one straight segment and an end is taken as an end of the first end of the conductive copper busbar. The first segment extends from the static contact in the direction opposite to the instantaneous action direction of the moving contact when the moving contact engages the static contact. The second segment is connected with the other end of the first segment, and extends towards the side of the first segment facing away from the moving contact.

An adapter assembly configured to be coupled to a surgical loading unit includes a switch, an elongated member, and an annular member. The switch is configured to be toggled in response to the surgical loading unit being coupled to the adapter assembly. The elongated member is in communication with the switch and is resiliently biased in a distal direction toward a locking position in which the switch is toggled. The annular member is disposed adjacent the elongated member and is rotatable between a first orientation, in which the annular member prevents distal movement of the elongated member, and a second orientation, in which the elongated member moves distally to toggle the switch.

An input device has operation shafts whose tips project through a first elongate hole and a second elongate hole formed through an upper plate portion of a case main body and that are movable along the upper plate portion of the case main body. An operation knob is movably attached to the tips of the operation shafts. The case main body is provided with elastic support pieces that deform following the movement of the operation knob and elastically support the operation knob.
