The term 'Bomb Parts' can be broken down into two crossword solutions: FUSES (5 letters) and Detonator (9 letters). FUSES are electrical components that are used to protect circuits from overloads. They are designed to break the circuit when a certain amount of current is exceeded, thus preventing damage to the circuit. Detonators are devices used to initiate an explosive reaction. They are usually triggered by an electrical impulse, and are used in bombs, mines, and other explosive devices.
