Abstract
The invention relates to the field of control devices, and particularly relates to a key structure. The key structure comprises at least one key and tact switches. The number of the tact switches is the same as that of the keys, and the positions of the tact switches is in one-to-one correspondence with those of the keys. A curing layer formed by curing of a mixture formed by liquid epoxy resin and a coagulant is arranged between each key and each tact switch. Each key abuts against the tact switch whose position is corresponding to that of the key through the curing layer. When a key is pressed, the key squeezes the tact switch corresponding to the key via the curing layer to enable the tact switch to be conducted to generate a signal to execute a preset function. The invention also relates to an electronic device comprising the key structure. Happening of phenomena that the key is sunk in the shell or the pressing stroke is over short when the key is pressed can be avoided.
