Claim 9:
10. A tandem sub for a perforating gun system, comprising:
a tubular housing comprising a longitudinal first end, a longitudinal second end opposite the first end, a central passage defined by an inner surface, wherein the housing is connectable to an outer housing of a perforating gun; and
an electrical pass-thru assembly configured to electrically connect to the perforating gun and comprising an electrically conductive signal bar having a longitudinal first end defining a first electrical contact of the tandem sub and configured to establish an electrical connection with a first electrical component separate from and external the tandem sub, and a longitudinal second end opposite the first end and defining a second electrical contact of the tandem sub that is longitudinally opposite and electrically connected to the first electrical contact and configured to establish an electrical connection with a second electrical component separate from and external the tandem sub, wherein neither the first end nor the second end of the signal bar is biased outwardly from the central passage of the tubular housing by a biasing member;
wherein the signal bar is coupled to the housing and a central axis of the central passage of the housing intersects the signal bar, and wherein both the first end and the second end of the signal bar comprises a concave receptacle.
