Abstract: A perforation gun that includes a safety mechanism to prevent detonation of the gun system.

Abstract: A coupler system comprising: a coupler; first, second, and third bulkheads included in the coupler; an electrical switch included in the coupler, wherein the electrical switch includes a printed circuit board (PCB); wherein the first, second, and third bulkheads respectively include first, second, and third bulkhead electric contacts, and the first, second, and third bulkhead electric contacts include no resilient members; wherein: (a) the first bulkhead is to couple to a first proximal electrical contact of a proximal connector of a perforation gun, (b) the second bulkhead is to couple to a second proximal electrical contact of the proximal connector of the perforation gun, and (c) the third bulkhead is to couple to a distal electrical contact of a distal connector of another perforation gun. The coupler includes proximal and distal sacrificial blast plates.

Abstract: A perforation gun that includes a monolithic bulkhead electrical contact that includes no resilient members but that is resiliently coupled to two perforating guns. The bulkhead electrical contact is configured to transmit a signal across a bulkhead from one gun to another gun.
