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).

摘要： A magnetically operated proximity device is provided with a pivotal armature formed as a hat in cross section with two L-shaped members, one being longer and greater in mass than the other. The horizontal leg of each L-shaped member is arranged such as to contact an electrical contact. The greater surface area of the L-shaped members enhance the sensitivity of the device, with the horizontal leg of each L-shaped member extending over a different pole face of a permanent magnet.

摘要： An arrangement is provided which is associated with a shaft of a device for indicating an operative or an inoperative state for the device. The arrangement includes a switch mechanism including a unitary enclosure having a cavity and a magnetic proximity switch in the cavity for producing electrical signals upon actuation t hereof. A mounting assembly is provided for supporting the switch mechanism as a unit. A shaft position indicator and control structure is associated with the mounting assembl y and the switch mechanism and such structure includes magnetic elements. Structure is pro vided for coupling the shaft position indicator and control structure to the shaft of the device. The unitary enclosure of the switch mechanism substantially encloses the cavity and the proximity switch in the cavity. The mounting assembly includes structure for pos itioning the switch mechanism in the vicinity of the magnetic elements of the shaft posit ion indicator and control structure. The shaft position indicator and control struct ure further includes structure which is connected to the shaft coupling structure for rotati ng the magnetic elements of the shaft position indicator and control structure to cause the magnetic elements of the indicator and control structure to travel adjacent to t he magnetic proximity switch of the switch mechanism for actuation of the switch upon moveme nt of the shaft of the device during the operative state of the device.

摘要： A magnetically actuated valve position sensing device for a linear or rotary valve comprising a switch housing completely enclosing one or more magnetic proximity switches. A mounting assembly comprises an outer housing for slideably receiving the switch housing, a magnetic rotary indicator on top the outer housing for indicating an open/close position for the valve and for actuating the switches in response to the shaft positions, and a shaft assembly for connecting the rotary indicator to the shaft of the rotary or linear valve. A bracket assembly mounts the switch housing to a stationary member of a linear valve and comprises brace members carrying magnets and connected to the linear valve shaft whereby the magnets actuate the switches upon translational movement of the brace members and the reciprocation of the linear shaft.

The horizontal leg (38, 40) of each L-shaped member cooperates with a respective electrical contact (28, 30).
