Abstract

비접촉형의 스위치에 스프링등의 기계적부재를 사용하는일 없이 양호한 조작감을 갖게한다.It provides a good feeling of operation without using a mechanical member such as a spring in a non-contact switch.

누름보턴(18)에 연결된 조작봉(14)에 철등 강자성체의 피흡인판(12)를 마련하고 케이스쪽에는 영구자석(16)를 마련한다. 조작스위치 (17)의 조작전에는 피흡인판 (12)은 영구자석 (16)에 흡착한 상태로 되어 있고, 누름보턴(18)을 양자의 흡착력 이상의 힘으로 조작하면, 피흡착판(72)은 영구자석 (16)으로 부터 이탈하여 검출부(20) 방향으로 이 동한다.The suction plate 12 of the ferromagnetic material such as iron is provided on the operating rod 14 connected to the push button 18, and a permanent magnet 16 is provided on the case side. Prior to the operation of the operation switch 17, the suction plate 12 is in a state of being adsorbed by the permanent magnet 16. When the push button 18 is operated with a force equal to or greater than the attraction force of both, the suction plate 72 is a permanent magnet. It moves away from (16) and moves in the direction of the detector 20.

검출부(20)에서는 이 동작을 조작봉(14)이 검출구멍 (22)에 끼워 통과 되늘것으로 검출한다. 피흡착판 (12) 이 영구자석 (16)으로 부터 이탈할때, 급격 하게 양자의 흡착력 이 저감하므로 사용자에게는 클릭감으로서 감지되어 양호한 조작감을 얻을 수 있다.The detection unit 20 detects this operation by passing the operating rod 14 into the detection hole 22. When the plate to be absorbed 12 is separated from the permanent magnet 16, the adsorption force of both is suddenly reduced, so that the user can be sensed as a feeling of click and a good feeling of operation can be obtained.

Claims

An operation switch having an operation unit 18 which is movable with respect to the switch main body and which generates a switch signal with respect to the movement of the operation unit 18, the suction unit 16 having a low magnetic resistance attached to the switch body. And a magnetic circuit provided between the suction unit 16 and the suction unit 16 to move a distance apart from the suction unit 16 by an operation of the operation unit 18. And a magnetic force generating portion for forming magnetic flux in the magnetic circuit having the suctioned portion 12 having low magnetic resistance and the suctioned portion 12 and the suctioned portion 16 as a path. Operation switch, characterized in that provided with.

The method of claim 1. An operation switch in which the suction unit 16 and / or the suction unit 12 serve as a piercing magnetic force generating unit formed by a lump magnet.

The suctioned part 32 is composed of the permanent magnet 39, and the permanent magnet giving repulsive force or suction force to the suctioned part 32 is located on the switch body side and operated by the operation unit 18. Operating switch placed in a position where the distance from) is small.
