Detonator assemblies for perforating gun systems

A perforating gun system, comprising:

• a cylindrical outer housing;
• and
• a charge carrier assembly receivable in the outer housing, wherein the charge carrier assembly comprises a charge carrier defining an interior configured to at least partially receive one or more shaped charges, a first endplate coupled to a first end of the charge carrier, and a second endplate coupled to a second end of the charge carrier;
• wherein the first endplate defines a switch receptacle for at least partially receiving an electrical switch and a detonator holder comprising a passage configured to receive a detonator whereby the detonator is at least partially received in the interior of the charge carrier and is configured to detonate the one or more shaped charges in response to receiving a firing signal from the electrical switch.
