摘要： A circuit breaker includes, for example, a housing, a stationary electrical contact attached to the housing, a movable arm operably movably attachable to the housing and a second end having an electrical contact releaseably contactable with the stationary electrical contact, and an actuator mechanism. The actuator mechanism includes a first biasing means for opening the electrical contacts, a second biasing means for closing the electrical contacts, and a yieldable support. The yieldable support is operable in a rigid configuration to support a compression force to prevent opening of the electrical contacts while the second biasing means is operable to apply the force to close the electrical contacts. The yieldable support is operable, by applying a tripping force, to transition the rigid configuration to the flexible configuration to withdraw support of the compression force and allow opening of the electrical contacts.

摘要： A circuit breaker includes a handle having OFF, ON and intermediate positions, and an extension. A blocking disk has a spring, and first, second and third surfaces. The handle and disk are co-pivotally mounted. The extension engages the third surface for rotation therewith. A pivot lever includes a first end adapted for engagement with a movable contact arm, and a second end adapted for engagement with the first and second surfaces. The first surface blocks the second end as the handle moves from OFF toward the intermediate position, and releases the second end to the second surface at the intermediate position. The first end blocks movement of the movable contact arm when the first surface blocks the second end, and releases the movable contact arm when the first surface releases the second end, thereby moving a movable contact toward a fixed contact in response to the bias of a spring.

摘要： Disclosed is an AC/DC switch for electric power tools which is free of bouncing at the time of turning on, still assuring the quick cutting-off of heavy current. In the improved electric switch the timing of turning-on and -off is guaranteed to be free from variation with age, which would be caused by wearing some projections of the switching mechanism and/or inconsistency in spring material. The electric switch, therefore, has a long-life and a high rating. The switching mechanism uses a reversal spring for quickly turning on and off in such a way that the movable contacts may be brought close to the stationary contacts prior to the turning-on, thereby permitting the turning-on subsequent to traverse of the reversal point without the bouncing of the movable contacts off from the stationary contacts when hitting thereon, and that movement of the movable contacts may be prevented before the reversal spring has stored an increased amount of energy, allowing the quick release of the stored energy to make the movable contacts leave the stationary contacts at a speed high enough to prevent appearance of electric arcs between the movable and stationary contacts, and hence prevent the wearing of the contacts.
摘要翻译：公开了一种用于电动工具的AC / DC开关，其在接通时不弹跳，仍然确保快速切断大电流。在改进的电开关中，保证了开启和关闭的时间不变，随着年龄的增长，这将由于穿过开关机构的一些突出和/或弹簧材料的不一致而引起。因此，电开关具有使用寿命长，额定功率高。切换机构使用反转弹簧来快速地打开和关闭，使得可动触头可以在接通之前靠近固定触点，从而允许在反转点的横穿之后接通，而没有可动触头在撞击时从固定触点弹起，并且可以防止可动触点的移动，因为反向弹簧已经储存了增加的能量，允许快速释放存储的能量以使可动触点以足够高的速度离开固定触点，以防止可动触点和静触点之间出现电弧，从而防止触点的磨损。

摘要： A mechanism for the rapid closure of electrical contacts on modular electrical apparatuses, particularly circuit-breakers is disclosed. The mechanism includes at least one movable electrical contact, which cooperates with at least one fixed electrical contact. The movable electrical contacts pivot with respect to a contact support. The movable electrical contacts are maintained in a rest position through at least one spring. The contact support is capable of rotary movement to alternatively position the movable electrical contacts in and out of electrical contact with the fixed electrical contact. The contact support is moved by a control lever, which may be manually actuated, acting through a toggle system, which imparts opposing rotary movements to the control lever and the movable electrical contacts. A cam, driven by the control lever and a finger, which is fixedly attached to each movable electrical contact, are caused to move in substantially the same direction, such that there is an intersection in the respective paths of motion of the cam and finger when the fixed and the movable electrical contacts are separated. The cam has a configuration and surface such that the cam and finger remain rotationally locked during a portion of the path of rotation of the control lever that is less than the portion of its path of rotation required to reach a stable position wherein the fixed and movable electrical contacts are in closed relationship to one another. The contact support continues to travel along its path, while the contact spring accumulates energy, which is dissipated only when contact between the cam and finger ceases. During a final stage of motion of the control lever, the cam is able to freely rotate relative to the control lever, with its range of motion being limited only by a stop element, positioned on the cam, which interposes itself between the cam and the control lever.

摘要： The battery section switch is switched between a terminal post and a main circuit using a contact arrangement. The contact arrangement can be locked in its closed position via a toggle spring device that acts directly on a free end of a contact spring. The toggle spring device is also coupled to the armature of an electromagnet system which, given excitation, releases the interlock and opens the contact arrangement. Given this battery section switch, the on-board network of a vehicle can be quickly switched current-free, given a collision or given a short-circuit, in order to reduce the risk of fire or in order to prevent a discharge of the battery given some other malfunction.

摘要： A mechanism for a circuit breaker includes a support lever insulated from a contact arm and a trip lever supported by a plate fitted with limited swivelling on a pivot. A mechanical link arranged between a toggle-joint and the contact arm includes a latching stop fixed on the plate. The stop is formed by a notch cooperating with a step of the trip lever to push the end of a toggle rod back to a retracted unlatched positon, as soon as the trip lever is actuated to the tripped position. The support lever is equipped with a locking arm having a sloping part cooperating with a pawl of the handle to form a high-speed contact closing device.
