Detonator for a perforating gun assembly

An end plate comprising:

• a first end defining a first face, with the first face abutting a charge tube of a perforating gun;
• a second end opposite the first end, and defining a second face;
• an opening along the second face configured to receive an end of a ground pin;
• a first through-opening and a second through-opening;
• a first bulkhead residing in the first through-opening configured to closely receive a signal transmission pin, wherein the signal transmission pin is configured to transmit electrical signals from the perforating gun, through the end plate, and to an addressable switch;
• a second bulkhead residing in the second through-opening configured to closely receive a detonator pin, wherein the detonator pin is configured to transmit a detonation signal from the addressable switch, back up through the end plate, and to a detonator;
• and wherein:
• the addressable switch comprises a first leg wire and a second leg wire;
• and
• the detonator is received within a compartment of the charge tube within the perforating gun.
