A keypad includes a base, an actuator, a first and second elastic member and a pivotal mechanism. The base has a through hole. The actuator is located in through hole to be moved between initial position and pressed position. The first elastic member is connected between the base and the actuator. The pivotal mechanism is pivotably and linearly movably disposed on the actuator to be moved between withdrawn position and protruding position. The second elastic member is connected between the actuator and the pivotal mechanism. The base has stop block and recess and the pivotal mechanism has tooth. While the actuator is moved to the pressed position, the tooth is stopped by the stop block so that the pivotal mechanism is pivoted and then linearly moved to the withdrawn position, and then enters into the recess, enabling the pivotal mechanism to the protruding position and press a switch.
