Abstract

PURPOSE:To enable the detection over the full angle range of 360 deg. by providing a spherical mobile electrode made of magnetic metal material attracted onto a permanent magnet rotatably contacting the first fixed electrode provided in contact with either pole of the permanent magnet and the ring-shaped second fixed electrode set securely fitted thereinto loosely. CONSTITUTION:A spherical mobile electrode 6 is housed inside a second fixed electrode 5 and placed rotatably on the first fixed electrode 3 provided in contact with the N pole of a permanent magnet 4 while attracted onto the permanent magnet 4 through the fixed electrode 3. The fixed electrode 5 is slightly larger in the inner diameter than the spherical mobile electrode 6. With such an arrangement, when there is no G applied on the sensor, the mobile electrode 6 is positioned at a magnetically stable point, not contacting the fixed electrode 5. When the sensor receives G in any direction of the arrow, the mobile electrode 6 gets in contact with the fixed electrode 5 electrically to connect the fixed electrodes 3 and 5. Thus, G is detected.
