摘要： A solenoid contactor arrangement facilitates soft contact between the movable and stationary contacts and provides for overtravel of an armature in a manner which ensures that good and consistent electrical contact is maintained between the movable and the stationary contacts. The movable contacts are carried on an axially reciprocable armature assembly and are afforded limited axial displacement relative thereto. The movable contacts are biased by a coil spring to a first position on the armature assembly in preparation for engagement with the stationary contacts. When that engagement occurs, the movable contacts stop, the spring yields, and further displacement of the armature assembly occurs until a stop on it firmly contacts and is stopped by a corresponding stop on the movable contacts. The spring is formed and positioned such that it does not dimensionally interfere with the firm contact between the movable contacts and the armature assembly. In the overtravel position, a predetermined small air gap is maintained between the armature and a pole piece to maximize the contact-engaging forces.
摘要翻译：电磁接触器装置有助于可动触点和固定触点之间的软接触，并以确保在可移动触点和固定触点之间保持良好且一致的电触点的方式提供电枢的超程。可移动触点承载在轴向往复运动的电枢组件上，并且相对于此可移动触点提供有限的轴向位移。活动触点被螺旋弹簧偏置到电枢组件上的第一位置，以准备与固定触点接合。当接合发生时，可动触点停止，弹簧产生，并且电枢组件进一步的移动发生，直到其上的止动器牢固地接触并且被可移动触点上的相应止动件停止。弹簧的形成和定位使得其不会在尺寸上干扰可动触头和电枢组件之间的牢固接触。在超行程位置中，在电枢和极片之间保持预定的小气隙，以使接触接合力最大化。

摘要： A coil mounting arrangement includes a coil wound on a bobbin and in turn disposed about a core which is mounted to a frame. The frame includes a base portion and a leg portion which extends upwardly therefrom at a right angle. A support collar extends upwardly from the upper surface of the frame base portion and encircles a mounting opening which extends through the frame base portion. The core is inserted downwardly into press-fitted engagement with the frame within the support collar and mounting opening. Insertion continues until the height of the top of the core correlates directly with a position on the frame leg portion, such as the pivot axis of an armature. The underside of the frame base portion remains smooth.

摘要： A bistable electrical contactor employs a one-piece permanent magnet plunger operating in conjunction with an aligned pole piece and a pair of oppositely-wound coils to afford pulse-operated bistable operation of the associated contacts. The coils are wound in opposition to provide respective opposite electromagnetic fields, one "aiding" and one "opposing" the inherent magnetic flux of the plunger. The plunger may be spring-biased toward one of its two bistable positions, typically the one in which the plunger is most remote from the pole piece. When an appropriate coil is briefly energized, the respective "aiding" or "opposing" force is respectively added to or subtracted from the inherent magnetic force of the plunger to cause the appropriate change of state. The pole piece is structured and positioned to facilitate interaction with the plunger. An adjustable stop arrangement minimizes bounce of resiliently-mounted contacts.
摘要翻译：双稳电气接触器采用一体式永磁铁柱塞，其与对准的极靴和一对相对缠绕的线圈结合操作，以提供相关联的触点的脉冲操作双稳态操作。线圈被相对地卷绕以提供相应的相对电磁场，一个“辅助”和一个“相对”的柱塞的固有磁通量。柱塞可以朝向其两个双稳态位置中的一个弹簧偏置，通常是柱塞最远离极靴的位置。当适当的线圈短暂通电时，相应的“辅助”或“相对”的力分别被加到或从柱塞的固有磁力中减去以引起适当的状态改变。极片被构造和定位以便于与柱塞的相互作用。可调节的止动装置使弹性安装触点的弹跳最小化。

摘要： An electrical equipment controller is provided with a delayed turn-off capability. A thermostat is in series with a control relay. The thermostat is further in parallel with the series combination of a relay latch contact and a first positive temperature coefficient (PTC) device. A second PTC device is connected in parallel with the control relay. The arrangement of first and second PTC devices provides a predeterminable drop-out relay including compensation for ambient temperature changes.

摘要： A push to start dual relay having master electrical contacts which are closed when a push button is depressed. The master contacts control the power supplied to a control circuit which, in turn, controls the power supplied to two relays. When the push button is released and either one or both relays are energized, the master contacts remain in the closed position. When the push button is released and both relays are deenergized, however, the master contacts are allowed to open.
