20090243771 | Electromagnetic switching device - This electromagnetic switching device comprises an electromagnetic device | 10-01-2009 |
20120092101 | NOISE DECREASING TYPE ELECTROMAGNETIC SWITCH - A noise decreasing type electromagnetic switch includes a buffer disposed between an end of a stationary core and an end of a movable core facing the end of the stationary core so as to allow the movable core | 04-19-2012 |
20120092102 | NOISE DECREASING TYPE ELECTROMAGNETIC SWITCH - A noise decreasing type electromagnetic switch includes a buffer disposed between a stationary core and a contact spring to electrically support a shaft and the stationary core. The buffer includes a buffering space therein. Accordingly, impact caused at the stationary core and the shaft can be effectively absorbed even by the buffering space as well as an elastic force of the buffer. The buffer is inserted in the stationary core for coupling so as to be prevented from being separated during operations, resulting in maintaining long-term durability. Also, the buffer may support the stationary core and a metal plate, whereby an assembly process can be simplified. | 04-19-2012 |
20130076464 | CONTACT SWITCHING DEVICE - An object of the invention is to provide a contact switching device that produces minimal hitting sound at the time of return. In the contact switching device, a movable iron core ( | 03-28-2013 |
20150022295 | ELECTROMAGNETIC CONTACTOR - The electromagnetic contactor includes a contact mechanism including a pair of fixed contacts disposed to maintain a predetermined interval and a movable contact disposed so as to connect to and separate from the pair of fixed contacts, and an electromagnet unit that drives the movable contact. The electromagnet unit includes a magnetic yoke enclosing a plunger drive portion, a movable plunger, a leading end thereof protruding through an aperture formed in the magnetic yoke and a peripheral flange portion being formed on a protruding end side, movement regulating portions that regulate movement of the peripheral flange portion of the movable plunger in an engaged position and released position of the contact mechanism, and a contact noise suppression member that suppresses contact noise when the peripheral flange portion of the movable plunger contacts the movement regulating portions. | 01-22-2015 |
20150042426 | ELECTRIC CONTACTOR WITH FLYWHEEL DRIVE AND METHOD OF SWITCHING AN ELECTRIC CONTACTOR ON AND/OR OFF - Disclosed is an electric contactor, in particular to be used in roadways, with the stator and an armature, the armature being connected with a contact region and being movable, during a switching-on operation and/or a switching-off operation of the contactor, from a first to a second position, the contact region being connected in at least one of these positions with a counter-contact region for closing an electric circuit, wherein a pushing device is connected with the armature which is rotational relative to the armature, wherein the pushing device at least temporarily pushes the armature supportively in the movement from the first to the second position of the switching-on and/or switching-off operation. | 02-12-2015 |
