Dual Diode Switch is installed in bulkhead body. It can pass negative (-) current to detonator in lower gun and positive (+)current to detonator in upper gun. The polarity of the upper and lower detonator connections cannot be changed by the operator. The white wire on a dual diode must always be connected to the shooting line. If the upper detonator and shooting line are reversed, both detonators will be fired at once.
