<p>The present invention relates to a safe. The safe according to the present invention comprises: a main body (10) having a storage space therein and an opening part formed on a surface thereof; a door (20) to open and close the opening part; a first electrolyte aqueous solution (31) through which a first current (1) flows; a switch unit (30) having a first coil (33) to generate a first magnetic field by the first current (1) and a plunger (35) to move from an on-position to an off-position by the first magnetic field; a key unit (40) having a second electrolyte aqueous solution (41) to react with the first electrolyte aqueous solution (31) to cause a sediment creation reaction and a neutral reaction to block the first current (1); and a locking unit (50) to move from a locking position to an unlocking position by a second coil (51) to generate a second magnetic field by a second current (2) flowing when the plunger (35) is disposed at the on-position and the second magnetic field, lock the door (20) when disposed at the locking position, and unlock the door (20) when disposed at the unlocking position.</p> |
