| 20100026427 | SWITCHING DEVICE - The invention is directed to a switch assembly which can be used in situation in which the switch accommodates the flow of high voltage current. An actuator assembly with moveable contacts is moved by a motor driven armature. The moveable contacts are in electrical engagement with the stationary contacts when the armature is in the first position, and the moveable contacts are spaced from the stationary contacts when the armature is in the second position. By angling the stationary contacts and moveable contacts, the linear motion of the armature causes the moveable contacts to move across the surface of the stationary contacts as the armature approaches the first position. As all of the movements of the assembly are in a direction parallel to the axis of the armature, the assembly can be manufactured and operated reliably in a relatively small space. In addition, the linear movement on the angled contact provides for a positive electrical connection even in adverse environments. | 02-04-2010 |

| 20120206220 | ELECTROMAGNETIC SWITCH DEVICE - In an electromagnetic switch, a magnetic plate, which forms a part of a magnetic circuit, and a bobbin of a second coil are assembled as one body by insert molding. An outer circumferential surface of the magnetic plate is adhered to an inner circumferential surface of a cylindrical frame made of metal. Because a large amount of heat energy generated in the second coil is transmitted to the magnetic plate, this can discharge the heat energy through the magnetic plate to the cylindrical flame. Because a mounting surface of the cylindrical frame is fixed to an end part of a starter housing case, it is possible to easily discharge the heat energy generated in the second coil through the cylindrical frame to the starter housing case. This structure prevents a temperature rise of the second coil and contributes entire-size reduction of the electromagnetic switch. | 08-16-2012 |
