| An electrical contactor has a first terminal having a fixed member with at least one fixed electrical contact, a second terminal, and a busbar connected to the second terminal. Two conductive movable arms are connected to the busbar and have a contact thereon. One arm is biased-closed to contact the fixed electrical contact in the absence of a separating force, and the other arm is biased-open to be spaced away from the fixed electrical contact in the absence of a closing force. The first and second movable arms and the busbar are arranged so that, when the contacts close, contra-flowing current urges the movable arms towards the fixed member to increase a force between the contacts. | ||||||

| The aim of the invention is to improve the breaking ability of vacuum interrupter in the medium- and high-voltage range. Said aim is achieved whereby the contact pieces which may be displaced relative to each other are moved with a relatively high speed during a first phase (S1) of the separation process until about null to null of the ultimate separation (extinction stroke Eh) and are brought to the given ultimate separation (isolating stroke Eh during a second phase (S2) with relatively low speed. | ||||||

| A vacuum switching apparatus for automatically performing a series of breaking and disconnecting operations includes a fixed electrode and a movable electrode mounted in a vacuum vessel. The movable electrode is sequentially movable between a closing position, an opening position and a disconnecting position. After the movable electrode passes through the opening position located between the closing position and the disconnecting position, the between-electrode opening speed of the movable electrode is reduced by a decelerating means. With this configuration, it is possible to move the movable electrode from the closing position to the disconnecting position without lowering the breaking performance, and hence to automatically perform a series of breaking and disconnecting operations. | ||||||

| A double pole, single throw switch for high current applications employs two sets of contacts, closed or opened by a toggle lever operating movable contacts on resilient arms into and out of engagement with fixed contacts. The chambers containing the sets of contacts are separated from a spring chamber which contains a flat spring to control the orientation of the toggle lever. Barriers between the spring chamber and each of the contact chambers prevents flashover between the contact sets. | ||||||
| 66 | AC Switch mechanism of the ball contact type | US237337 | 1981-02-23 | US4320271A | 1982-03-16 | Ronald G. Munroe |
| An AC switch mechanism utilizes a ball contact to which generally linear motion is imparted by a rockable actuator having a spring providing downward contact force and a spring acting ball pusher leg to provide a snap action. In a single pole configuration disclosed as a typical and basic embodiment of the switch, the ball contact in one extreme position engages and extends as a conductive bridging element between bared conductor wires of an electric cable. The cable thus dispenses with the need for assembling separately made switch terminals with the other components of the mechanism. When moved from the "on" position to its other extreme, "off" position, the ball moves onto sloping ramps having a slight, gradual inclination relative to the lengths of the conductor wires. The construction offers a slow break to provide a minimum arc length before the zero point of the AC cycle, a characteristic of great importance in the design and operation of AC switches. Further benefits are obtained by providing a simultaneous two-point break to divide the arc and therefore reduce the arc's outward extension and tracking of the adjacent areas. The design is additionally effective to produce a fast bounce, free make to minimize contact deterioration caused by arcing at the "make" point of the switching cycle. The need for silver alloy contacts is eliminated by providing a continuously moving point of arc termination which cools the contact surface, minimizing the volume of vaporized material, and condenses out the copper vapor during the zero point of the half cycle. | ||||||

| An electrical switch comprising a drive mechanism for moving a switch component at a pre-selected variable speed. A movable additional mass is connected at a drive branched-off the drive mechanism of the moved switch component, said branch drive possessing a transmission ratio which is variable as a function of the position of the moved switch component.BACKGROUND OF THE INVENTIONThe present invention relates to a new and improved construction of an electrical or electric switch having a drive mechanism for moving a switch component at a speed which varies in a pre-selected manner.For instance when separating the contacts of certain switches it can be necessary to displace the moved contact, i.e. the moved switch component at a variable speed in order to take into account the different requirements regarding the cut-off or separation operation e.g. the extinguishing of the arc and the gentle slowing down during as rapid as possible switching operation. In order to be able to cope with the foregoing there have already been used drives (for instance Maltese cross drives or elliptical gear drives) possessing a transmission ratio which varies depending upon the relative position of the drive and the moved switch component. In order to reduce the possibly arising surges, there have been provided balancing oscillating masses in the transmission chain of the drive between the power source and the moved switch component. However, increased drive power is necessary due to the friction and mass of such drives. On the other hand, there are in direct conflict with one another the demands regarding smooth transition and the high power requirements.SUMMARY OF THE INVENTIONHence, it is a primary object of the present invention to provide an improved construction of an electrical switch which is not associated with the aforementioned drawbacks and limitations of the prior art proposals.Another and more specific object of the present invention aims at the provision of a new and improved construction of switch having a drive which, with relatively small drive power and as simple as possible construction, renders possible the realization of a predetermined course of the speed of the moved switch component.Now in order to implement these and still further objects of the invention, which will become more readily apparent as the description proceeds, the invention contemplates the provision of a new and improved construction of an electrical switch of the previously mentioned type which is manifested by the features that a movable additional mass is connected to a drive branched-off from the positive drive mechanism of the moved switch component, this branched-off drive or branch drive possessing a transmission ratio which is variable as a function of the position of the moved switch component.The fact that the additional mass is connected via the aforementioned branch drive possessing variable transmission ratio renders it possible for the inertia of the additional mass, depending upon the transmission ratio of the drive, to have a different effect at different points in time of the switching operation and different amounts of drive energy are tapped-off of the drive mechanism of the moved switch component and absorbed or again returned back to the system, so that there can be realized an almost random variation of the course of the speed of the moved switch component.Now since it is possible to construct the moved switch component and its direct drive as simple and mass-free as possible, it is possible to maintain small the drive power. However, it is possible to select the additional mass to be relatively large, so that the same can develop a different degree of action depending upon the transmission ratio of the branched-off or branch drive. If the momentary transmission ratio of the branch drive is adjusted such that the additional mass does not or hardly moves, then the drive energy acts completely upon the moved switch component and markedly accelerates the same. However, if the transmission ratio is altered such that the additional mass must be moved more rapidly, then such is initially braked owing to the inertia of the entire drive whereupon it tends to again store energy as an oscillating mass, if after reaching equilibrium the drive power (e.g. in the case of a power or energy storage) again decreases. Also in this stage it is possible to influence the effect of the additional mass upon the moved switch component by changing the transmission ratio.There can be connected at least one further movable additional mass after the additional mass by means of at least one further drive possessing a variable transmission ratio. This results in further influencing the course of movement and thus the course of the speed of the moved switch component without requiring complicated drives.In accordance with a simple constructional embodiment of the invention there can be used as the branched-off or branch drive lever drives, for instance such where it is possible to change the lever arm ratio or leverage during the course of the rocking or pivoting of the lever in such a manner that the lever engages into a slot of a rotatable cam disk. The cam disk can be part of an additional mass.As the power or energy source of the drive there can be used all known systems, such as springs, hydraulic devices, pneumatic devices, motors, and so forth, just to mention a few noteworthy possibilities. | ||||||

| The invention relates to a rocker unit for moving a displaceable contact (2a) of a switching device (3). Said unit comprises a drive rod (9) for moving the displaceable contact (2a), one end of said rod being connected to the displaceable contact (2a) and the other end to a bolt (8), a gate plate (5), which guides the bolt (8) in a sliding manner between a first position that corresponds to an open state of the displaceable contact (2a) and a second position that corresponds to a closed state of the displaceable contact (2a) and a coupling device (4) that can be displaced by means of a drive unit and that is connected to the gate plate (5). The aim of the invention is to employ a rocker unit (1) of this type to safely extinguish an arc that is created when the displaceable contact (2a) is opened. To achieve this, the gate plate (5) comprises a rest zone (7b), which holds the bolt (8) in an intermediate position between the first position and the second position. | ||||||

| A contact thermostatic switch has a dished, snap-acting bimetallic disc (5) cantilevered from one end of a diameter whereat the edge of the disc is loosely retained between a housing moulding (1) and a metal cap (6) secured to the moulding. At the other end of this diameter, the edge of the bimetallic disc engages a pip (4d) on one end of a lever (4) which is pivotally-mounted in the housing at its other end. When the bimetallic disc (5) snaps to its oppositely dished configuration, it moves the pivotally-mounted lever (4) so as to determine the condition of a set of switch contacts by virtue of the end of the lever (4) which carries the pip (4d) also having depending fingers (4c) which abut a moving-contact carrying leaf spring (2b) of the switch. The cantilevered mounting of the bimetallic disc and its interaction with the lever enables a smaller than conventional disc to be used, with consequent significant cost savings, without prejudicing the operation of the switch. | ||||||

| The aim of the invention is to improve the interrupting capacity of a vacuum switch. to achieve this, the contact parts (4, 5) that can be displaced in relation to each other are separated at a variable speed. Separation takes place in such a way that during a predetermined time period a predetermined distance between the contacts is not exceeded. To prevent said predetermined distance from being exceeded, a braking element is allocated to the vacuum circuit breaker. | ||||||

An electrical contactor (10) has a first terminal (12) having a fixed member (30) with at least one fixed electrical contact (32), a second terminal (14), and a busbar (16) connected to the second terminal (14). Two conductive movable arms (58, 60) are connected to the busbar (16) and have a contact (50) thereon.
