1. A vibration switch comprising:

  • an electrically insulating housing with a chamber formed therein and extended in a longitudinal direction;

    two attachment means disposed at one end of the chamber respectively;

    two spring means received in the chamber and attached to one of the two attachment means respectively;

    two electric contact terminals electrically connected to one of the two spring means respectively; and

    an electrically conductive inertial weight received in the chamber and disposed between the two spring means;

    wherein when the vibration switch is jerked in the longitudinal direction, the inertial weight is capable of moving by inertial force from an initial position to positions where the inertial weight contacts or disengages one of the two spring means, making the vibration switch change from an initial state to a switch-on state or a switch-off state;

    the inertial weight is capable of returning to the inertial position by the spring force of the two spring means.
