Abstract

PURPOSE:To realize the long life of a magnetic switch by obtaining self-restoring force having a long stroke and a clicking sensation without using a mechanical movable part such as a spring in a switch. CONSTITUTION:In a structure wherein return force is obtained by suction force between a permanent magnet 2 and a board to be attracted 4, a part, folded and expanded in a direction in which the permanent magnet 2 moves, is provided at the edge of the board 4. Consequently even the permanent magnet 2 is separated from the board 4, the folded part is positioned at near to the permanent magnet 2 to ensure attraction force, making the permanent magnet 2 returnable in a long stroke. Also a clicking sensation can be obtained by utilizing the discontinuous weakening of the attraction force when the permanent 2 is parted from the folded part.

The operation and action of the third embodiment configured as described above will be described. In the magnetic switch of this embodiment, when the key top 6 is pushed and the operating rod 7 is pushed down, the permanent magnet 2 provided at the lower end of the operating rod 7 pushes the contact 10 to bring it into contact with ON. It is a thing. In such an operation, the change in the pushing force of the operator while the operation rod 7 moves is as follows. First, suction cup 4
While the permanent magnet 2 is moving downward in the U-shape, the gap 9
Due to the action of, a weak pressing force is sufficient. Next, at the point where the permanent magnet 2 is pushed down to the position where the permanent magnet 2 is removed from the U-shape, the attraction plate 4 and the permanent magnet 2 are loops through which the magnetic force lines pass, so a force to keep them acts and the operation is performed. A force that pushes back the rod 7 works, and a pressing force that opposes it is required. Further, when the operating rod 7 is pushed downward, the permanent magnet 2 and the attraction plate 4 are separated from each other, and the above force for pushing back the operating rod 7 is suddenly weakened. The force of pushing back the operating rod 7 weakens discontinuously, which is a click feeling. The restoring force is obtained by the U-shaped tip portion of the suction plate 4 and the attraction force of the permanent magnet 2, and can return to the original state. As described above, according to this embodiment, a click feeling and a restoring force can be obtained without using a movable mechanism such as a spring, and a long life can be expected.

In the above embodiment, an example in which a bent portion (extended portion) is provided along the moving direction of the permanent magnet 2 at a part of the edge of the suction plate 4 has been shown, but the size and structure allow it. Obviously, if necessary, a bent portion (extended portion) may be provided on the entire edge portion. The method of forming the extended portion is not limited to the method of bending. Further, in the above-mentioned embodiments, the push button type switch has been described as an example, but it is obvious that the present invention can be applied to a micro switch type and other types of switches that require self-restoring force. As described above, the present invention can be applied in various ways in accordance with the gist thereof and can take various embodiments.
