1. A detonation module for a perforation tool, the detonation module comprising:
an end configured to receive and couple to a ballistic transfer unit of the perforation tool;
a detonator;
a switch circuit disposed in a fluid-sealed housing and electrically coupled to the detonator;
a shielding circuit coupled to the switch circuit;
an annular electrical contact electrically coupled to the switch circuit; and
an annular, electrically conductive, compressive member configured to directly couple to the ballistic transfer unit of the perforation tool and form a compressive electrical connection between the annular electrical contact and the ballistic transfer unit, wherein the annular electrical contact is disposed between the detonator and the annular, electrically conductive, compressive member.
