System for safely opening/closing power window of vehicle

A system for safely opening/closing a power window of a vehicle, comprising:

• a main opening/closing device for provision adjacent to a driver seat so as to open and close a window of a passenger seat;
• and
• a sub opening/closing device for provision adjacent to a passenger seat so as to open and close a window of a passenger seat,
• wherein the main opening/closing device comprises
• a main plate on which a plurality of main electrodes are disposed, and
• a main switch movably disposed on the main plate, and contacting selected main electrodes of the plurality of main electrodes such that either of an up-signal or a down-signal is output, and
• wherein the plurality of main electrodes comprises
• at least one main ground electrode for generating a signal, and
• a main center electrode electrically connected to the sub opening/closing device, and electrically connected to the at least one main ground electrode by the main switch, and disposed on a predetermined portion of the main plate so as to be prevented from being electrically connected to the main ground electrode when the main switch moves;
• wherein the at least one main ground electrode comprises:
• a first main ground electrode disposed apart from a left side of the main center electrode by a first predetermined gap;
• and
• a second main ground electrode disposed apart from a right side of the main center electrode by the first predetermined gap;
• wherein the plurality of main electrodes further comprises:
• a first up-signal outputting main electrode disposed apart from a left side of the first main ground electrode by a second predetermined gap;
• a first down-signal outputting main electrode disposed apart from a left side of the first main ground electrode by a third predetermined gap, and disposed apart from a lower side of the first up-signal outputting main electrode by a fourth predetermined gap;
• a second down-signal outputting main electrode disposed apart from a right side of the second main ground electrode by the second predetermined gap;
• and
• a second up-signal outputting main electrode disposed apart from a right side of the second main ground electrode by the third predetermined gap, and disposed apart from a lower side of the second down-signal outputting main electrode by the fourth predetermined gap;
• and
• wherein the main switch comprises:
• a main frame formed of a material with conductivity;
• at least one first main contact point disposed on the main frame, and contacting the main center electrode at a first position;
• a second main contact point disposed on the main frame, contacting the first main ground electrode at the first position, and contacting the first up-signal outputting main electrode when the main frame moves to a left side by the second predetermined gap;
• a third main contact point disposed on the main frame, contacting the first main ground electrode at the first position, and contacting the first down-signal outputting main electrode when the main frame moves to the left side by the third predetermined gap;
• a fourth main contact point disposed on the main frame, contacting the second main ground electrode at the first position, and contacting the second down-signal outputting main electrode when the main frame moves to a right side by the second predetermined gap;
• and
• a fifth main contact point disposed on the main frame, contacting the second main ground electrode at the first position, and contacting the second up-signal outputting main electrode when the main frame moves to the right side by the third predetermined gap.
