<p>PURPOSE:To obtain a joy stick type switch having high sensitivity and high reliability, by superposing two permanent magnets in a repulsing state, and forming a magnetism generating body. CONSTITUTION:Cylindrical permanent magnets 12, 13 being in a repulsing state are provided so as to coincide with an axial core of an operating body 11, in a cavity part of a spherical resin body 15. A lead switch 17 provided on a part of a supporting member 19 is made to execute an on-off operation against an inclined angle theta from the center position of the operating body 11. A repulsing state is generated by a magnetism generating body 14 by two polymerized magnets and a pair of contact parts of the lead switch 17, and the switch 17 is opened. When this position is changed, a magnetic field from one magnet operates on the pair of contact parts, absorptivity operates, and the switch 17 is closed. The inclined angle theta of the operating body during this time is obtained in a slight difference, and the sensitivity is raised remarkably.</p> |
