摘要： A magnetically operated proximity switch is provided with a pivotal armature 24 formed as a hat in cross section with two L-shaped members (34, 36) one (36) being longer and greater in mass than the other (34). The horizontal leg (38, 40) of each L-shaped member cooperates with a respective electrical contact (28, 30). The device includes permanent magnets (14, 16) mounted below the members (34, 36) with the two L-shaped members (34, 36) being in close proximity with magnet poles of different polarities. Because of a greater air gap existing between the shorter leg 34 and its respective magnetic pole than between the longer leg 36 and its magnetic pole and because of the greater mass of the longer leg 36, the longer leg is normally held in engagement with its electrical contact 30. However, upon approach of a body of ferro-magnetic material, some of the magnetic flux through the longer leg 36 is shunted through such body, reducing the magnetic force on the longer leg 36 allowing the magnetic force on the shorter leg 34 to pivot the armature into position in which the shorter leg engages its contact 28.

摘要： Un dispositif de détection de la position d'une vanne à actionnement magnétique est destiné à une vanne linéaire ou rotative comprenant un boîtier de commutateur (18) renfermant entièrement un ou plusieurs commutateurs magnétiques de proximité (96, 98). Un ensemble de montage (10) comprend un boîtier externe (44) recevant de manière coulissante le boîtier à commutateur (18), et un indicateur magnétique rotatif (14) sur le dessus du boîtier externe (18) pour indiquer la position ouverte/fermée de la vanne et pour actionner les commutateurs (96, 98) en réponse aux positions de la tige, et un ensemble tige (41) pour connecter l'indicateur rotatif (14) à la tige de la vanne rotative ou linéaire (16). Un ensemble de fixation (50) permet de monter le boîtier à commutateur sur un organe fixe ou sur une vanne linéaire (16) et comprend des éléments de fixation (56, 58) portant des aimants (66) et connectés à la tige (41) de la vanne linéaire, de sorte que les aimants (66) actionnent les commutateurs (96, 98) lors du mouvement de translation des éléments de fixation (56, 58) et du mouvement alternatif de la tige linéaire (41).
