To provide a vibration sensing switch having sufficient detection accuracy, without being excessively sensitive.
This vibration sensing switch includes a housing constituted so that a hollow part is partitioned into a plurality of divisions and the plurality of these divisions are respectively divided into an ordinary position and an abnormal position, a plurality of conductive balls arranged one by one in the plurality of divisions, constituted as the housing in its size, existing in the ordinary position existing in a corresponding division when there is no vibration and operating by moving to the abnormal position existing in the corresponding division or reciprocating between both positions in response to vibration when there is the vibration, and a plurality of sets of terminal units respectively inserted by a pair into the abnormal position in the plurality of divisions from the outside of the housing and transmitting an electric signal by electrically continuing both these insertion end sides by contacting with the corresponding conductive balls when the plurality of conductive balls operate, and is provided for sensing the vibration by electrically continuing both the plurality of conductive balls by contacting with the insertion end side of the terminal unit of the corresponding set when receiving the vibration.
