Abstract

The invention relates to an input device capable of improving contact sensitivity, which comprises a plurality of key units, a circuit board and a plurality of pressed units corresponding to the key units, wherein each key unit comprises a soft key cap and a hard pressed block formed at the bottom of the soft key cap; the circuit board comprises a plurality of conductive contact assemblies; each conductive contact assembly is provided with a first polar zone and a second polar zone; each pressed unit comprises a positioning diaphragm and a conductive shrapnel positioned between the positioning diaphragm and the circuit board; when each key unit is loosened, the conductive shrapnel is only in contact with the first polar zone; and when each key unit is pressed, the pressed salient point of each hard pressed block is pressed downwards to enable the conductive shrapnel to be deformed to conduct the first polar zone and the second polar zone, thus the pressing stroke sensitivity and the pressing hand feeling are improved by each hard pressed block and the conductive shrapnel.

Description

technical field [0001] The invention relates to an input device, in particular to an input device capable of improving contact sensitivity. Background technique [0002] refer to figure 1 , a conventional input device 1 includes a plurality of key units 11, and a circuit board 12 positioned under the key units 11, each key unit 11 includes a soft keycap (keycap) 111, and is formed on the soft keycap The conductive soft material layer 112 on the bottom surface of 111, the circuit board 12 includes a plurality of conductive contact groups 121 corresponding to the conductive soft material layer 112, each conductive contact group 121 has a first pole area 122 and a second pole area 123, press the The soft keycap 111 makes the conductive soft material layer 112 contact the conductive contact group 121 to make the first and second electrode regions 122 and 123 conduct. [0003] Since the button material is made of soft material, the pressing stroke is unstable and invalid pressi...
