A preformed coil interface includes conductive jumper wiring in a molded insulator and a contactor coil terminal end and an overload relay output terminal end. The contactor coil terminal end includes a first and a second jumper wiring connection points. The overload relay output terminal end includes a third, a fourth, a fifth, and a sixth jumper wiring connection points. The first jumper wiring connection point extends through the molded insulator to the fifth jumper wiring connection point at the overload relay output terminal end. The second jumper wiring connection point extends through the molded insulator to the sixth jumper wiring connection point at the overload relay output terminal end. And, the third jumper wiring connection point and the fourth jumper wiring connection point are jumpered internal to the molded insulator.

A mating connector assembly for electrically coupling modular electrical devices. A first stationary connector is coupled to a first rigid circuit board positioned within a first housing of a first modular electrical device. The first floating connector is coupled to a flexible circuit element positioned within a second housing of a second modular electrical device, the flexible circuit element coupled to a circuit board positioned within a second housing of a second modular electrical device. The second housing includes a first latch plate adjustable between an unlatched position and a latched position, the first latch plate including a biasing member, such that, when the first modular electronic device is pressed together with the second modular electronic device, the biasing member applies a force to the first floating connector during a latch plate transition position to ensure that the first floating connector has fully mated with the first stationary connector.

A programmer for an appliance having a line power switch and a plurality of program switches sequentially actuated by a cyclic cam mechanism. The program switches are latched to the actuated condition and uplatched independently of the cyclic mechanism by electrically energized release mechanisms, individually controlled by an electronic controller having a microcomputer which employs a user selected programmed sequence.

A system is provided for sensing data and for conveying the data to a network via an RFID tag. The sensed data may be provided as simply two-state single-bit data or as multi-bit data converted from analog values. The sensor used in the system alters an RFID tag address to include one or more bits of data derived from the sensor signal. A reader may then prompt or interrogate the RFID tag and obtain both the unique identification of the sensor as well as the sensed data as one or more bits in the address. The reader may then convert the data to a network message and place the message on a conventional network for interpretation used by remote devices.
摘要:
An enclosure housing has a first wall defined as a molded polymeric construction, a first latch defined as a one-piece construction with the first wall, a second wall defined as a molded polymeric construction, and a second latch defined as a one-piece construction with the second wall. A circuit board is connected to the enclosure housing and includes a board member defined by a periphery. The periphery includes: (i) a first tab defined by a first inclined ramp surface and a first locking face that lies transverse to the first inclined ramp surface, wherein the first tab is engaged with the first latch; and, (ii) a second tab defined by a second inclined ramp surface and a second locking face that lies transverse to the second inclined ramp surface, wherein the second tab is engaged with the second latch.
摘要:
A programmer for controlling the actuation and deactuation of a plurality of load function switches. A motorized cam drum track moves a follower pivoted about a fulcrum pin. A solenoid controlled by a microcomputer slidably moves a bar operable to selectively latch and unlatch the fulcrum pin. When latched, the pin causes the follower to pivot and effect the actuation and deactuation of the associated switch in response to the cam track and the follower, when the fulcrum is unlatched, leaving the switch unmoved. The solenoid controls latching and unlatching independently of the cam drum rotation.
