摘要： The invention provides a bi-stable electric relay. Electrical contact members CM1, CM2 are in contact with the respective electrical terminals T1, T2. The contact members CM1, CM2 provide electric contact in the first stable state, and are disconnected in the second stable state. A slider SL with a magnetically conducting armature AM can move between two stable positions and the slider SL can thereby break electrical contact between the contact members CM1, CM2 in one stable position. A permanent magnet PM arranged with a magnetically conducting element ML1, ML2 for generating a magnetic flux to magnetically attract the armature AM of the slider SL, so as to keep the slider SL in the stable position, where the contact members CM1, CM2 are disconnected. An electromagnet EM or solenoid, preferably sharing the magnetically conducting element ML1, ML2 with the permanent magnet PM, is used to switch between the stable states by being energized by an electric current to either attract the armature AM of the slider SL or to cancel the attraction force provided by the permanent magnet. The electromagnet EM should be powerful enough to counteract the magnetic attraction force of the permanent magnet PM in the disconnected state. The contact members CM1, CM2 are designed such that repelling Lorentz forces serve to force their electric contact points against each other, thereby allowing the relay to be used for high currents without damage problems. The relay can be integrated in an electricity meter to allow remote breaking of delivery of electric energy to a consumer.

摘要： Das Klappankerrelais ist mit einem Kontakthebel (2) ausgestattet, der den Doppelkontaktniet (1 ) trägt und schwenkbar so gelagert ist, daß er unter der Einwirkung einer einseitig angreifenden Zugfeder (5) und weiterhin eines Stößels (9), der seinerseits unmittelbar durch den Klappanker betätigt wird, in zwei stabile Endlagen gekippt wird. Der Mittelkontakt (1,2) zeigt deshalb ein Rückstell- oder Schnappverhalten, wobei ein wesentlich größerer Kontakthub durchgeführt wird, als es etwa bei unmittelbarer Betätigung des Mittelkontaktes durch den Klappanker möglich wäre. Die Übersetzung des Klappankerhubes durch den über einen Stößel (9) betätigten Kontakthebel kann beispielsweise das Zehnfache und mehr betragen. Die Kontaktkraft wird dabei nicht verringert. Die den Kontakthebel (2) in die Ruhelage zurückholende Zugfeder (5) erstreckt sich etwa in Richtung der Kontaktebene und hat einen sehr geringen Platzbedarf, der eine Vergrößerung der baulichen Abmessungen nicht mit sich bringt. Der Klappanker des Relais ist ferner in seinen Endlagen an einem energieverzehrenden Material abgestützt und schaltet deshalb prellarm.

摘要： Embodiments of the present disclosure provide a load switch. The load switch comprises: a wireless transmission circuit configured to generate a first control signal in response to a control command signal from a remote device; a control circuit coupled to the wireless transmission circuit and configured to generate a second control signal in response to a reception of the first control signal from the wireless transmission circuit; a switching circuit coupled to the control circuit and comprising a relay arranged in a circuit, the switching circuit being configured to control a state of the circuit by controlling the contacts of the relay in response to a reception of the second control signal. The load switch achieves intelligent wireless control with the same size as a conventional common contactor. In addition, the load switch can monitor and acquire the information about the states of the circuit and the contacts, and voltage and current of the circuit, so that the user can understand various information of the circuit and the load switch in time. This improves both user experience and safety of electricity.

In particular, when the mobile contact (144) is in the operative first position, the mobile contact (144) and the fixed contacts (162) are connected electrically, and when the mobile contact (144) is in the operative second position, the mobile contact (144) and the fixed contacts (162) are disconnected.
The contactor further comprises a sensor (1468) for detecting actuation of the mechanical means (24, 242-254) before these interrupt the electrical connection between the fixed contacts (162), and a control device (1462, 1466, 1470) configured for driving the electromagnetic control device (142) in such a way that the mobile contact (144) is pushed into the operative second position when the sensor (1468) indicates that the mechanical means (24, 242-254) have been operated.
