Bridged bulkheads for perforating gun assembly

A method of detonating explosive charges associated with a perforating gun, comprising:

• providing a bridged bulkhead assembly, comprising:
• a first bulkhead;
• a signal transmission pin residing within the first bulkhead;
• a second bulkhead;
• a detonator pin residing within the second bulkhead;
• and
• a bridge fixedly connecting the first bulkhead with the second bulkhead,
• connecting the bridged bulkhead to a carrier end plate such that the first bulkhead extends into a first opening of the carrier end plate and the second bulkhead extends into a second opening of the carrier end plate;
• sending a detonation signal from a surface, down an electric line, and into a wellbore;
• further sending the detonation signal through a perforating gun and through the carrier end plate by means of the signal transmission pin;
• still further sending the detonation signal into an addressable switch, wherein the addressable switch determines whether the detonation signal is addressed to the perforating gun;
• identifying that the detonation signal is addressed to the perforating gun, and in response, sending a detonation signal back through the carrier end plate by means of the detonator pin;
• and
• sending the detonation signal to a detonator to initiate explosive charges residing within the perforating gun.
