PROBLEM TO BE SOLVED: To thin an entire push-button switch using a lead switch.SOLUTION: A flange 3 that limits movement of a push-button 2 includes a leaf spring pressing bar 31. In a leaf spring 4, a proximal end portion 42a is fixed to a leaf spring fitting part 11 and a supporting point part 42c is supported by a leaf spring support base 12. The leaf spring is brought into contact with the spring pressing bar 31 at a pressed point 42d that is close to the supporting point part 42c, a magnet 5 is mounted in a distal end portion 42b, and the magnet 5 is made close to or separate from a lead switch 6 by an action of the leaf spring 4 with operation of the push-button 2, such that the lead switch 6 is turned on and turned off. The push-button 2, the lead switch 6 and the magnet 5 are disposed side by side, movement of the magnet 5 is enlarged and a stroke of the push-button 2 is reduced. As a result, a thin-shape push-button switch can be realized.SELECTED DRAWING: Figure 1
【課題】リードスイッチを使用した押しボタンスイッチ全体を薄型化すること。【解決手段】押しボタン2の動きを制限する鍔3に板バネ押さえバー31を備え、板バネ4は基端部42aが板バネ取り付け部11に固定され、支点部42cが板バネ支持台12で支持され、支点部42cに近い被押圧箇所42dでバネ押さえバー31に接し、先端部42bに磁石5が取り付けられ、押しボタン2の操作に伴う板バネ4の作用で磁石5がリードスイッチ6に接近しまたは離れ、これによりリードスイッチ6をオンオフする。押しボタン2と、リードスイッチ6と、磁石5とを並べて配置すると共に、磁石5の動きを拡大して、押しボタン2のストロークを小さくする。その結果、薄型形状の押しボタンスイッチを実現することができる。【選択図】図1
