    摘要: A power on/off mechanism of a plug-in unit driven by an insertion/ejection device in a printed circuit board (PCB) which is adapted to various power switch on/off switches in accordance with a characteristic of a plug-in unit, thus reducing manufacturing costs and easily maintaining parts. The mechanism includes a power switch on/off lever having a protrusion formed in one end thereof which is inserted into a guide groove formed in a center portion of the handle when inserting/ejecting the plug-in unit and a jaw formed in another end thereof for receiving the power switch lever. The power switch on/off lever is inserted into a lever engaging hole formed in the bracket, and the power switch lever is position in the interior of the jaw. When plug-in unit is inserted into the sub-rack, one end of the power switch on/off lever is inserted into the guide groove formed in the handle, the protrusion of the lever is lowered along the guide groove, the other end of the lever is lifted, and the power switch lever in the interior of the jaw of the lever turns to the on state. When ejecting the plug-in unit from the sub-rack, one end of the power switch on/off lever is ejected from the guide groove of the handle, the protrusion of the lever is lifted along the guide groove, and the power switch lever turns to the off state from the on state through a dead point.
