Input device with touch function and key trigger function

The invention relates to an input device with touch function and key trigger function. The input device comprises a bottom plate, a plurality of keys and a touch sensing module, wherein a key cap of one of the plurality of keys is arranged above the bottom plate to generate a pressing travel; the touch sensing module is used for generating a touch signal when the key cap is pressed, and the pressing travel does not exceed a preset value so as to execute corresponding touch instruction; the touch sensing module is also used for generating a key trigger signal when the pressing travel of the key cap exceeds the preset value so as to execute corresponding key trigger instruction; the input device also comprises a circuit board which is used for generating the key trigger signal when the pressing travel of the key cap exceeds the preset value so as to execute corresponding key trigger instruction. According to the input device, the touch signal and the key trigger signal correspondingly generate by using the diff
