摘要： With proper handling, Gallium-Indium-Tin eutectics are suitable for use as a substitute for mercury in switch applications. The eutectics should be acid washed to prevent oxidation of the metal components of the eutectic while in the switch housing and, further, the switch housing should be filled with an inert gas. Preventing oxidation ensures long term performance of the switch. In addition, provisions need to be made to prevent wetting of the switch housing by the eutectic. Experiments have shown that acid washing of metallic switch housings prior to adding the Gallium-Indium-Tin eutectic reduces or eliminates wetting by the eutectic. In addition, experiments have shown that coating the walls of the switch housing with a fluoropolymer coating prevents wetting by the eutectic.

摘要： A reed switch comprising a sealed capsule which includes a movable armature consisting in a beam of magnetic material having two pole ends capable of alternate contacting engagement with a respective of two distinct stationary contacts when the armature is pivoting in a longitudinal axial plane. The armature is suspended symmetrically to the ends of a helicoidal spring which extends axially around the armature beam and which is fixedly positioned inside the capsule by means of a cylindrical annular electrode. The coacting surfaces of the pole ends and the stationary contacts are provided with spots made of a material which cannot be wetted by the mercury also included in the capsule. Magnetic means in various embodiments are also provided to create the initial magnetic condition according to the mode of switching operation desired.

摘要： A miniature mercury switch, comprising an enclosure including a tube having a mercury wettable inner surface, within which a contact carrying shuttle is movable along the axis of the tube. The shuttle is not mercury wettable except for a slot or groove extending between its ends and for contact surfaces at its ends, but it rides on a mercury layer attached to the inner surface of the tube. Secured within and extending into the ends of the tubes are unwettable rods of magnetic material having stationary end contacts which are mercury wettable. The contacts on the shuttle ends include tantalum or niobium spacers extending beyond mercury wettable end contact surfaces on the shuttle, the spacers accepting the impacts when the relay contacts operatively close, which implies that the wettable contact areas on the shuttle ends closely approach the stationary end contacts, so that the mercury layers coalesce, but the wettable surfaces do not impact. The quantity of mercury within the enclosure is only sufficient to form a layer of mercury on the mercury wettable surfaces within the enclosure, but insufficient to form a pool of mercury, or to cover unwettable surfaces while wettable surfaces are covered, and the slot or groove in the shuttle facilities transfer of mercury from end to end of the enclosure, which prevents pooling at either end of the enclosure concomitant with depletion at the other, due to imbalance of mercury transfer during relay operation. Stationary contacts are, for open contact condition, spaced from movable contacts, by mercury unwettable surfaces of the enclosure, and the quantity of mercury available is insufficient to cover these unwettable surfaces and also to form a mercury layer on the mercury surfaces.
摘要翻译： 一种微型水银开关，包括一个外壳，它包括一个具有汞可湿润内表面的管，其中一个接触运输梭可以沿管的轴线移动。 除了在其端部之间延伸的槽或槽以及其端部的接触表面之外，梭子不是水银可湿润的，而是穿过附接到管内表面的汞层。 固定在管的末端并延伸到管的端部是不可控制的磁性材料棒，其具有可湿汞的固定端接头。 穿梭端上的触点包括延伸超过梭子上的水银可湿性端接触表面的钽或铌间隔物，当继电器触点闭合时，间隔件接受冲击，这意味着梭子端部上的可湿接触区域紧密接近固定端 接触，使汞层聚结，但是可湿性表面不会受到影响。 外壳内的汞量仅足以在外壳内的汞可湿性表面上形成一层汞，但不足以形成汞池，或者在可湿性表面被覆盖的情况下覆盖不可浸泡的表面，以及槽或凹槽 在穿梭设施中从外壳的一端到另一端传送汞，这样可以防止由于继电器操作期间汞转移的不平衡而在外壳的任一端集合，同时造成另一端的损耗。 固定触点为开放接触状态，与可动触点间隔开，由外壳的不可凝水的表面组成，并且可用的汞量不足以覆盖这些不可否认的表面，并且还在汞表面上形成汞层。

摘要： An electric relay including a movable armature wherein the armature includes an electric conducting portion adapted to engage and bridge spaced electrical contacts at a predetermined armature position. During the conducting position of the armature, a mercury applicator mounted on the armature is immersed within a small reservoir of mercury wherein small particles thereof adhere to the applicator upon removal of the armature from engagement with the electrical contacts. Such disengagement of the armature from the contacts positions the applicator adjacent the effective contact surfaces, for random engagement therewith, wherein small mercury particles are transferred to the contact surfaces, to utilize mercury in establishing the electrical circuit between the contacts and the armature electrical conducting portion during subsequent cycles of operation.
