Abstract
The vibration switch includes a housing with a chamber formed thereon and extended in a longitudinal direction. Two attachment means are disposed at two ends of the chamber respectively. Two spring means are received in the chamber and attached to the two attachment means respectively. Two electric contact terminals are electrically connected to the two spring means respectively. An electrically conductive inertial weight received in the chamber and disposed between the two spring means. 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.
