ABSTRACT:
A switch device for a screw button is disclosed. The switch device includes a slowdown box with a switch base, which consists of two sets of concave gears with appropriate spacing located on the axial plane around the outer brim, each set having a plurality of switch concave gears. The side on which the switch gears located is formed as a inclined surface, which is used to coordinate with a plurality of switch concave gears corresponding to the switch convex gears where the respective axial surface of the switch base in the switch block are set. The switch block thereby controls the switch convex gears to engage or disconnect with the switch concave gears when rotating. The motion of the output axis in radial direction is manipulated to determine whether the vibrating block fixed on the output axis can vibrate when the output axis is pressed and rotates to induce vibration because engaged with the vibrating base. Therefore, the rotating ring, inner ring gear, sun gear, and rotating ring of the slowdown box in the prior arts are eliminated to simplify the whole structure.
