PROBLEM TO BE SOLVED: To provide a compact and low-cost vibration switch endowed with superb switching sensitivity with little operation failure. SOLUTION: The vibration switch includes a housing 2 made of an insulating material and equipped with a penetrating space 2A with two openings 20, 21 opposed, a spherical movable conductive member 3 inserted into the space in free movement, a first electrode member 4 arranged at the housing and equipped with two electrode parts so arranged to have the movable electrodes separated from each other at one side and the other side of the openings, a second electrode member 5 equipped with a hole for the movable conductive member to be in and out of contact with. Both electrode parts are integrated with a coupling part 4C extended in one direction from both electrode parts. COPYRIGHT: (C)2010,JPO&INPIT
