TGM-E TYPE TRANSFER SWITCH is a change-over switch which changes over the power sources of 2 systems by an electromagnetic coil only instantaneously and supplies electric power to load. Electric power is supplied to the electromagnetic coil at the time of change-over action. An instantaneous exciting machine holding type mechanism that power consumption is normally zero has been adopted for the purpose of holding the contact condition of contacts mechanically after action.

TGM series are adopted in a wide application field i.e. change over of commercial power and emergency one (generator, battery etc.) represented by co-generation system and commercial power for many years.
