Electromechanical relay with data collection cover
An electromechanical relay is provided with a housing, a relay assembly within the housing, and a data collection cover enclosing the relay assembly within the housing. The data collection cover includes sensing members that extend in toward the relay assembly and engage disconnect switches of the relay assembly. The sensing members transmit analog signals to an analog-to-digital converter that converts analog signals to digital signals. The cover then stores, displays and/or communicates the digital information.
Base plate, electronic component, and method
A base plate for an electronic component, in particular an electronic relay, has a plate-shaped base body, in particular made of plastic, and at least one electrical contact. The electrical contact fully extends through the base body. At one end the electrical contact forms an electrical terminal of the electronic component, in particular of the relay. At another end the electrical contact has an electrically conductive connection section which can be connected to a circuit board without soldering, in particular by being pressed into the circuit board, to form a permanent electrical connection.
Single coil magnetic latching relay control circuit and method
A control circuit and method for a single coil magnetic latching relay is provided in the present disclosure. The circuit includes: a first control circuit (21) and a first single coil magnetic latching relay coil (22). The first control circuit (21) includes: a first transistor (211), a first diode (212), a second diode (213), a first capacitor (214), a second capacitor (215), a first resistor (216) and a second resistor (217) and the first control circuit (21) is configured to control the first single coil magnetic latching relay coil (22) to enter a preset state and/or maintain the preset state.
DISCONNECTING DEVICE FOR INTERRUPTING A DIRECT CURRENT OF A CURRENT PATH AS WELL AS A CIRCUIT BREAKER
A disconnecting device interrupts a direct current of a current path containing a hybrid switch which has a current-carrying mechanical contact system and a semiconductor switching system connected in parallel thereto. The contact system has a fixed contact and a moving contact. The moving contact is mounted on a contact bridge being coupled to a drive system moving the moving contact in a switching movement from an open position into a closed position resting against the fixed contact with a contact force. A first magnet element is mounted on the contact bridge and spaced apart from a stationary second magnet element by an air gap such that, when a current flows through the contact bridge, a magnetic field is produced in the first magnet element and the first and second magnet elements are magnetically attracted. The attraction produces a magnetic force directed in the same direction as the contact force.
COMPACT ELECTRICAL DEVICE REMOTE CONTROLLER
An electronic system that controls existing electrical devices, such as those typically found in buildings such as electrical outlets and single-pole single-throw switches, which can include a circuit board upon which is mounted a connector block, a controllable switch, an AC-to-DC power converter, electrically conductive jumpers, and a control circuit. The electronic system further provides a radio means for communicating with a system controller, which may be local or remote, which provides commands for controlling the electrical device. The electronic system is configured to compactly connect with the existing electrical device by way of the electrically conductive jumpers and to fit within the confines of a single gang electrical box.
Relay
A relay includes: a housing, a base plate, and a driving device, connected to the base. At least one stationary contact group is provided on the housing. The stationary contact group includes two stationary contacts insulated from each other. At least one stationary contact in the stationary contact group includes an upper terminal and a lower contact are included. The upper terminal and the lower contact are isolated from each other and electrically connected by a fuse. The base plate is provided in the housing and can switch between on and off positions. The base plate, when being in the on position, contacts the stationary contact group for the electrical conduction of the two stationary contacts in the stationary contact group, and, when being in the off position, is isolated from the stationary contact group for disconnecting the electrical conduction of the two stationary contacts in the stationary contact group.

A system include a vehicle having a motive electrical power path and a power distribution unit (PDU). The PDU includes a current protection circuit disposed in the motive electrical power path, the current protection circuit including a thermal fuse and a contactor in a series arrangement with the thermal fuse, and a high voltage power input coupling having a first electrical interface for a high voltage power source. The high voltage power output coupling includes a second electrical interface for a motive power load. The current protection circuit electrically couples the high voltage power input to the high voltage power output, and the current protection circuit is at least partially disposed in a laminated layer of the PDU. The laminated layer includes an electrically conductive flow path disposed between two electrically insulating layers.
RELAY CIRCUIT AND ELECTRIC JUNCTION BOX
A relay circuit includes a relay and a current divider. The relay includes a coil and a contact. The contact is configured to switches on and off a supply of power to a load that is configured to operate with power supplied from a direct-current power supply through conduction of the coil. The current divider is connected between the contact and the load and configured to split a current supplied from the power supply to the load. The current divider incudes a resistor and a capacitor connected in series and grounded.
High power, multi-phase, AC power contact arc suppressor

Each dual unidirectional arc suppressor includes a first phase-specific arc suppressor configured to suppress arcing across the associated contacts in a positive domain, a a second phase-specific arc suppressor configured to suppress arcing across the associated contacts in a negative domain, and a coil lock controller, configured to be coupled between a contact coil driver of the power contactor, configured to detect an output condition from the contact coil driver and inhibit operation of the first and second phase-specific arc suppressors over a predetermined time.
ELECTROMAGNETIC RELAY AND TERMINAL BLOCK
An electromagnetic relay and a terminal block each include a voltage converter. The voltage converter is located adjacent to a coil and electrically connected to first coil terminals and second coil terminals. The voltage converter converts a power supply voltage input through one of the first coil terminals to a set value different from the input power supply voltage and outputs the power supply voltage to an electromagnet through one of the second coil terminals.
