Abstract
【解決手段】異なる極性となるように配列された複数の磁石6−1〜6−3の内、中央の磁石6−2を二個のホールIC9−2,9−3で検知するので、磁石とホールICとが1対1に個別的に対応する構成に比べて、磁石の個数を減らして小型化を図ることができる一方、ホールICの数を維持して、信頼性を確保することができる。
【選択図】図1
Description
アクチュエータ21の4個の磁石23−1〜23−4は、隣合う磁石が交互に異なる極性になるように配置される一方、スイッチ本体22の4個のホールIC25−1〜25−4は、検知対象となる磁石23−1〜23−4の極性に応じて、各磁石23−1〜23−4の一方の磁極にそれぞれ対向するように配置される。各ホールIC25−1〜25−4は、検知対象となる磁石23−1〜23−4が近接して検知領域に入ると、検知出力を与える。
各ホールIC9−1〜9−4は、検知対象となる極性の磁石6−1〜6−3が近接して検知領域に入って、磁束密度が閾値を超えると、ローレベルの検知出力を与えるものである。
