Abstract: A touchpad press device includes a support unit having two first sides interconnecting between two second sides, and first engaging members proximate to the second sides. A touch unit with a touch switch is disposed above the support unit, and a transmission unit is disposed between the support unit and the touch unit. The transmission unit includes peripheral plates, each of which is disposed above one of the second sides and has second engaging members, and a pressing plate to trigger the touch switch. When one of the peripheral plates is pressed downward through the touch unit, the other peripheral plate turns upward so that the second engaging members thereof engage the respective first engaging members to limit the other peripheral plate from moving further upward.

Abstract: A pressing device includes a base board, an upper board unit that is disposed over the base board, and an intermediate unit that is disposed between the base board and the upper board unit. The upper board unit includes a panel, a circuit board, and a tact switch. The intermediate unit includes a middle portion that corresponds in position to the tact switch, a surrounding frame member, and a plurality of interconnecting board members. When the upper board unit is pressed, at least one of the interconnecting board members is deformed, and the middle portion is driven to convert the tact switch from an initial state to a triggered state.

Abstract: A pressing device for a touchpad includes a base unit, an upper board unit, and an intermediate unit. The upper board unit includes a trigger switch aligned with the abutment portion of the base unit. The intermediate unit has a surrounding frame member, two positioning members, two connecting members, and a actuating member that are interconnected by a plurality of linking ribs. When the upper board is pressed at a position above one of the surrounding frame member and the connecting members, one of the connecting members is moved relative to the actuating member by virtue of the linking ribs, and the actuating member provides a force to convert the trigger switch from an initial state to a triggered state.

Abstract: A pressing device includes a base board unit including at least two coupling members, an upper board unit including a trigger switch and at least two engaging members, and two interlocking members disposed between the upper board unit and the base board unit. Each interlocking member has at least one coupling portion coupled with a respective coupling member, at least one engaging portion coupled with a respective engaging member, and at least one locking set. The locking set of one interlocking member is coupled with the locking set of the other interlocking member. When the upper board unit is pressed, the interlocking members are pivoted and the trigger switch is converted from an initial state to a triggered state.

Abstract: A touch input device includes a frame unit, a circuit unit and a touch pad. The circuit unit includes a circuit board, a dome-shaped actuating member including an actuating portion and a resilient metal sheet connected between the actuating portion and the circuit board, and a noise reduction member having a main body connected to the resilient metal sheet, made of an elastic material and formed with a recess surrounding the actuating portion. A touch surface of the touch pad is touchable to push the circuit unit toward the block member, such that the actuating portion contacts the block member to deform the resilient metal sheet to electrically connect the actuating portion with the circuit board.

Abstract: A trigger device includes a circuit board, an arched sheet, and a noise-reducing unit that includes first and second electroconductive sheets respectively connected to first and second nodes of the circuit board. The arched sheet is mounted to the second electroconductive sheet and is pressible from a preset state to a bent state, with the arched sheet being deformed and proximate to the first electroconductive sheet, and further from the bent state to a contact state, with the second electroconductive sheet being compressed and with a central portion of the arched sheet being brought into contact with the first electroconductive sheet to thus electrically connect the first and second nodes.

Abstract: A touch input device includes a base board, a circuit module having a free end portion and a connecting end portion, a metallic connecting member and an annular, metallic frame. The connecting member includes a positioning portion fixedly mounted to the connecting end portion of the circuit module, and an elastic arm extending from the positioning portion away from the connecting end portion and toward a free end portion in such a way to define a coupling groove that indents away therefrom. The frame is spaced apart from the circuit module and includes a coupling portion that is embossed from a side of the frame proximate to the connecting member, and that has a coupling block coupled to the coupling groove of the elastic arm.

Abstract: A touch input device includes a base board, an upper board, and a touch unit. The base board has an elongate opening having opposite opening ends respectively defined by two end walls. The upper board is disposed on and above the base board and includes a touched sensing member. The touch unit is mounted to the base board and includes two positioning seats, a contact element, and two resilient arms. The positioning seats respectively abut against the end walls. The contact element corresponding in position to the touched sensing member is disposed. Each resilient arm interconnects the contact element and a respective one of the positioning seats.

Abstract: A touch input device includes a base board unit and an upper board unit. The base board unit includes opposite side ribs, opposite top and bottom surfaces, an intermediate portion disposed at the middle of one side rib, two flanking portions flanking the intermediate portion and two slots formed respectively through the flanking portions. The base board unit includes two resilient arms extending from the intermediate portion into the slots, respectively. The upper board unit is disposed on and above the base board unit and includes opposite sides correspond respectively in position to the side ribs, and two touch sensing modules respectively correspond in position to and spaced apart from the resilient arms.
