Beschrieben wird eine berührungslos arbeitende Näherungsschalteinrichtung mit einem zwei miteinander in Kontakt bringbare Schaltglieder aufweisenden magnetfeldabhängigen Schalter zur Sensierung der relativen Annäherung bzw. Entfernung eines Körpers an den bzw. von dem Schalter. Es ist ein Permanentmagnet zur Erzeugung eines den Schalter betätigenden Magnet­feldes vorgesehen.

Gemäß Fig. 1 ist der Permanentmagnet (14) bezüglich des Schalters (11) ortsfest angeordnet. Der Permanent­magnet (14) und der Schalter (11) sind in einem gemein­samen Gehäuse, welches auf einem Arbeitszylinder (1) angeordnet ist, untergebracht. Als zur Betätigung des Schalters (11) dienender, wenigstens zum Teil aus einem ferromagnetischen Werkstoff bestehender Körper dient der Kolben des Arbeitszylinders 1. Der Schalter (11) ist mit dem Permanentmagenten (14) magne­tisch leitend verbunden. Beim Vorbeiführen des Kolbens am Schalter (11) und dem Permanentmagneten (14) wird der Magnetfluß im Schalter (11) verstärkt, wodurch die Schaltglieder (9, 12) des Schalters (11) miteinander in Kontakt gebracht werden.

182 Magnetische Betätigungsvorrichtung mit Flussmodulation EP79104182.5 1979-10-29 EP0012812A1 1980-07-09 Helinski, Edward Frank

Magnetische Betätigungsvorrichtung, bei der das Betätigungselement (12; 48, 58) durch einen einseitig gerichteten magnetischen Fluß in gespannter Position gehalten wird, dessen Flußdichte in seiner Amplitude sich zyklisch mit der Zeit ändert und durch selektive Erregung einer Kompensationswicklung (30; 61) ausgelöst wird, wodurch dem die Haltewirkung auslösenden Fluß dann entgegengewirkt wird, wenn die Flußdichte geringer ist als ihr Maximalwert. Der Maximalwert des Halteflusses kann dabei so hoch gewählt werden, daß diese Flußdichte ausreicht, das ausgelöste Betätigungselement (12; 48, 58) in seine gespannte Position zurückzuziehen.

189 Magnetically-triggered proximity switch US13159263 2011-06-13 US08362859B2 2013-01-29 Joel Pearce; Robert L. LaFountain; Michael J. Simmons
A magnetically-triggered proximity switch includes a cylindrical switch body and a first magnet non-movably secured within the switch body. The proximity switch also includes a pivoting cross arm. A second magnet may be movably disposed within the switch body, and the second magnet may be rigidly connected to the cross arm. When a magnetic target is not located within a specified range of the second magnet, the first magnet attracts the second magnet, thereby pivoting the cross arm into a first switch position and closing a first circuit. However, when the magnetic target is located within the specified range, the magnetic attraction between the target and the second magnet is greater than between the second magnet and the first magnet. The second magnet is displaced towards the target away from the first magnet, thereby pivoting the cross arm into a second switch position.

191 Switch device US12368717 2009-02-10 US07978037B2 2011-07-12 Tomio Yamada; Tatsumi Ide; Yoshinori Ota
A movable contact positioned in a sealed case is moved together with a movable contact spring provided with an armature by a magnetic shunt body which is moved outside the sealed case. The movement of the movable contact (movement of the movable contact spring) due to the movement of the magnetic shunt body is based on the change of the magnetically attracting force of a magnet with respect to the armature through a pair of yokes. The movable contact spring is provided with a bent portion which is bent in spaced-apart relation to the armature, the bent portion being provided between a fulcrum portion at a time when the movable contact spring moves and a portion where the armature is provided.

195 Non-contact auxiliary switch and electric power apparatus incorporating same US10335664 2003-01-02 US07034644B2 2006-04-25 Peter K. Moldovan; Edward L. Wellner; Michael R. Larsen; Paul J. Rollmann; Xin Zhou; John R. Skibinski; Randal D. Gazdecki
The auxiliary switch includes a non-contact sensor, such as a Hall effect device, that is switched by the condition of a magnetic field. The magnetic field condition is effected by a movable contact indicator that moves between open and closed positions with the separable contacts of the electric power apparatus. A magnet may be attached to the movable contact indicator, or the movable contact indicator can be magnetized to form the magnet. Alternatively, the moving contact indicator can intercept or not intercept a magnetic field produced by a fixed magnet spaced from the sensor. The Hall effect device may be mounted on the outside of the nonmagnetically permeable housing of the electric power apparatus, or inside if there is sufficient room. In either case, no mechanical coupling is required for the sensor.

197 Electric switch assembly and related method of use US749867 1991-08-26 US5200726A 1993-04-06 Lee E. Leppo; James A. Campo
An electric switch assembly for use with a magnetic reed switch includes a trigger that is movable with respect to a housing between an open position and a closed position and that includes a trigger magnet. The switch assembly further includes a second magnet, fixed relative to the housing, that is located adjacent the first magnet when the trigger is in the open position. The magnets are oriented such that their magnetic fields tend to cancel each other when the trigger is in its open position. This provides an increased disparity in the magnetic field reaching the magnetic reed switch between the open position and closed position and eliminates the need for precision alignment and individual adjustment of the magnetic reed switch at the point of manufacture.
198 Probe for detecting the presence of magnetic material in a ground hole US211441 1988-06-24 US4902976A 1990-02-20 Douglas J. Belshaw; Donald A. Toon; Peter F. Kuryllowicz
In use, the probe (1) is dropped into a ground-hole (3), for the purpose of detecting the depth of the steel casing (16) of the hole. The probe comprises a long, slim, tubular housing (2) made of stainless steel. Attached inside the housing is a springy stalk (10) made of PVC. The stalk is deflectable laterally, and carries a magnet (11) at its free end. The magnet responds to the steel, and causes the stalk to deflect while in the presence of the steel. The housing, and a stainless steel sleeve (12) around the magnet, comprise a pair of electrical contacts, which break apart and send a signal to the surface when the magnetic influence disappears. The probe is suspended on a cable (4) which is calibrated to indicate the depth of the probe when the signal is received.

200 Magnetic circuit device US755264 1985-07-15 US4596971A 1986-06-24 Yasuyuki Hirabayashi; Hiroyuki Sono
A magnetic circuit device suitable for use in a magnetic catch having a switching function, a slide switch or a sensor for detecting locations of a movable member has been found. The magnetic circuit device comprises a main permanent magnet (1) having a pair of magnetic poles (N, S) on opposite faces, a pair of yoke pieces (2) lying on the faces, a movable piece (4) made of magnetic material capable of engaging with first ends of the yoke pieces (2), and a sub-permanent magnet (6) movably disposed near second ends of the yoke pieces (2) opposite to the first edges so that when the movable piece (4) is attracted to the first ends, the sub-permanent magnet (6) is attracted to the second ends, and when the movable piece (4) is made break away from the first ends, the sub-permanent magnet (6) breaks away from the second ends. Movement of the sub-magnet (6) can be utilized to control electrical connection of contacts (8A, 8B) of a switching mechanism.
