Perforating gun with detonation module

A perforating apparatus, comprising:

• a first perforating gun having a first carrier having a first interior;
• a second perforating gun having a second carrier connectable to the first carrier, the second carrier having a second interior, the second carrier further having an opening communicating with the second interior;
• and
• a detonation module including:
• an end plate having a first passage and a second passage, the first passage extending from a planar end face of the end plate and the second passage extending from a circumferential surface of the end plate;
• a first electrical contact assembly positioned at a first end in the first passage;
• a second electrical contact assembly positioned at a second end in the first passage;
• and
• an addressable switch seated in the second passage, the addressable switch including a body and a seal disposed circumferentially around the body, the addressable switch electrically coupling the first electrical contact assembly to the second electrical contact assembly when seated in the second passage.

A method of assembling a perforating apparatus, comprising:

• providing a first perforating gun having a first carrier having a first interior;
• providing a second perforating gun having a second carrier connectable to the first carrier, the second carrier having a second interior, the second carrier further having an opening communicating with the second interior;
• providing a detonation module that includes:
• an end plate having a first passage and a second passage, the first passage extending from a planar end face of the end plate and the second passage extending from a circumferential surface of the end plate, wherein the end plate includes:
• a first electrical contact assembly positioned at a first end in the first passage, a second electrical contact assembly positioned at a second end in the first passage, and
• a body that includes a portion of a signal communication circuit configured to convey signals between the first electrical contact assembly and the second electrical contact assembly;
• positioning a first end of the end plate in the first perforating gun and a second end of the end plate in the second perforating gun;
• connecting the first perforating gun to the second perforating gun;
• and
• electrically coupling the first electrical contact assembly to the second electrical contact assembly by inserting the body through the opening of the second carrier and disposing the body at least partially in the second passage after the first perforating gun is connected to the second perforating gun.
