A generator generates electricity when the generator is pressed and has a stator, a rotor, a drive shaft, a biasing member and a top cover. The rotor is mounted in the stator and has a central hole with at least one key. The drive shaft is slidably mounted in the central hole in the rotor base and has at least one spiral groove in which the at least one key on the rotor is mounted. The biasing member is mounted between the base and the drive shaft to provide a restitution force to the drive shaft when the drive shaft is pressed down manually. The top cover has a central bore through which the top of the drive shaft non-rotatably extends. Accordingly, movement of the drive shaft causes the rotor to rotate relative to the stator and generate electricity.
