Claims (2)
- 弾性薄板金属からなり、上面視円形の外周縁が傾斜面となった円錐状周縁部で、この円錐状周縁部に囲まれた部分が上方に膨らんだ球面状部となり、上記球面状部への押圧操作により上記球面状部が節度感を伴って下方突状に弾性反転し、上記押圧解除により元の上方に膨らんだ状態に弾性復帰する可動接点であって、上記円形の両端部が平行な直線で切り欠かれて中心線に対称な形状に形成されると共に、上記切り欠かれた直線状縁部と円形の縁部との交点部が円弧状に面取りされた略小判形状に形成され、上記押圧操作による弾性反転時の押圧力(P1)と弾性復帰時の押圧力(P2)との関係((P1−P2)/P1)が少なくとも40%以上になるように設定されている可動接点。
- 外径寸法(φD)に対する、両端部を切り欠いた直線の平行間隔(W)の割合(W/D)が、62%以上で、かつ、円弧状の面取りの半径(R)が、0.8〜1.2mm、円錐状周縁部の傾斜角度が、8度〜20度である請求項1記載の可動接点。
