This invention discloses a smart key exclusively for telephone, calculator, remote controller and camera, which comprises a recession having a sensor point disposed on a special instruction press key or at a local position of a press key, such that when a user's finger touches the desired press key, pr presses a predetermined position, or the force of the pressing finger drives the muscle into the recession, a sensing effect is produced with the finger. Therefore a predetermined signal is produced by the press key to achieve the control purpose for a predetermined function. Thus, the operation is not only gentle and easy, but also makes the signal produced by the press key a non-contact structure with the contact point. The press keys will not have oxidized contract points or poor contacts even after a long time of use.
