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.
