| 20120105178 | ELECTROMAGNETIC SOLENOID - An electromagnetic solenoid having an electromagnetic coil, a fixed iron core, a movable iron core, and a spring coil. The spring coil, arranged between the fixed and the movable iron core, supplies a spring force to the movable iron core toward an opposite direction of the fixed iron core along the axial direction. A magnetic attraction surface and a fitting part are formed in at least one of the fixed iron core and the movable iron core. The magnetic attraction surface is contacted with the fixed iron core when the movable iron core reaches the fixed iron core. An outer peripheral surface of the fitting part, apart from the magnetic attraction surface by a predetermined distance along the axial direction, is engaged with the spring coil. The most outer peripheral part of the magnetic attraction surface is positioned inside rather than the most outer peripheral part of the fitting part. | 05-03-2012 |

| 20120081199 | ENERGY-SAVING ELECTROMAGNETIC SWITCH DEVICE - An energy-saving electromagnetic switching device in the present invention includes a housing, and an electromagnetic assembly and a movable magnetic pole within the housing. The movable magnetic pole connects a resilience means which engages with the movable magnetic pole to control the electromagnetic switching device switched on and off. At least one locking assembly is set between the movable magnetic pole and the housing, via which the electromagnetic switching device can automatically and repeatably change from an on-state to an off-state if the electromagnetic assembly is momentarily energized. The electromagnetic switching device is energy-saved, has higher automatization degree, simple operation, and lower cost. | 04-05-2012 |
| 20130027158 | Electric Switching Device With Ultra-Fast Actuating Mechanism and Hybrid Switch Comprising One Such Device - A switching device with an ultra-fast actuating mechanism for opening electric contacts comprising a propulsion coil and a conducting disk. A stationary contact collaborates in the closed position with a movable contact, said contacts being moved to the open position by repulsion of the conducting disk. A biasing device generates a closing force to hold said electric contacts in the closed position. Latching means of the movable contact in the open position comprise a magnetic yoke having an attraction coil providing an attraction force of a magnetic movable armature. The movable contact is supported by a contact-bearing support comprising drive means designed to collaborate with the magnetic movable armature to cause movement thereof, when movement of the movable contact takes place. | 01-31-2013 |
| 20150084724 | INTEGRATED HIGH VOLTAGE CONTACTOR AND SERVICE DISCONNECT - An integrated contactor/service disconnect assembly according to an exemplary aspect of the present disclosure includes, among other things, a stationary contact, a movable contact selectively movable relative to the stationary contact and a service disconnect unit configured to block the movable contact from contacting the stationary contact. | 03-26-2015 |
