Abstract: A touchpad includes a touch board, a base, and a spring sandwiched between the touch board and the base. The touch board is mounted on an outmost side of the touchpad for touching thereon. The touch board includes a sleeve post. A base includes a pillar. A switch is secured on the base and located between the base and the touch board. A spring is sandwiched between the touch board and the base. One portion of the spring is retained on the sleeve post, and another portion of the spring is retained on the base. The touch board is slidable relative to the base between a first position and a second position. In the first position, the touch board and the switch is separated by the spring. In the second position, the touch board compresses the spring towards the base, and the switch is triggered by the touch board.
