The touch control module can also be extended to other consumer electronics products as a touch pad peripheral (a single touch pad or a combined use with a keyboard) or as other interaction equipment. The touchpad module includes a circuit board 10, a touchpad 20, a linkage assembly, and a base plate 30.

Wherein, the back of the circuit board 10 is provided with a touch switch 11. A touch pad 20 is attached to the front surface of the circuit board 10. The linkage assembly comprises a bracket 41 and a balance bar 42, wherein the bracket 41 is connected to the back surface of the circuit board 10, and the balance bar 42 is rotatably connected to the bracket 41. The base plate 30 is engaged with the bracket 41. When the balance bar 42 rotates around the first direction X relative to the bracket 41, the circuit board 10 is driven to rotate relative to the bottom plate 30, so as to trigger or release the trigger switch 11. Wherein the first direction X is a length direction of the touch pad 20. In the present embodiment, the tact switch 11 is located at a position corresponding to the center position of the holder 41, facilitating the triggering.

When the touch pad 20 is pressed, the balance bar 42 rotates around the first direction X, and drives the circuit board 10 to rotate along the rotation axis 90 toward the direction close to the bottom plate 30, and the trigger switch 11 completes triggering after reaching the set stroke. When the touch pad 20 is released, the balance bar 42 rotates in the first direction X, and the circuit board 10 and the touch pad 20 are driven to rotate along the rotation axis 90 in a direction away from the bottom plate 30, so that the tact switch 11 is flicked to release the trigger. No matter the left side or the right side of the front surface of the touch pad 20 is clicked, the displacement of the two sides of the touch pad 20 is linked through the balance rod 42, so that the trigger stroke is the same when the touch pad 20 is pressed left and right, the touch pad does not deform when being clicked, the left and right clicking touch feeling is consistent, the touch pad does not need to be long and laborious, the clicking is easy, the feedback is clear, and the defect that the touch pad 20 deforms when being used for a long time can be effectively overcome.
