A separable electrical connector assembly includes mating rod connector and bore switch modules. The bore switch module includes a grasping bore contact member for electrically engaging with a rod contact member which is included in the rod connector module. The rod contact member includes an arc follower at its engaging end. The assembly includes means for providing an operator, during a make operation, with a modified dwell position immediately following which electrical engagement of the rod and bore contact members is made. At the modified dwell position, further insertion of the rod contact member into the switch module is met by a noticeable resistance. At the modified dwell position, a predetermined distance separates the arc follower and the grasping bore contact member. In one embodiment, the bore switch module includes two axially spaced annular grooves respectively containing a gas sealing ring and a stop ring. The rod contact member includes two spaced annular recesses. These annular recesses are positioned such that, at the modified dwell position, the stop ring wedges between one recess of the rod contact member and the stop ring groove of the switch module. This provides the noticeable resistance to further insertion of the rod contact member through the stop ring and into the switch module. A vigorous closing force to the rod connector module overcomes the stop ring resistance, permitting further insertion of the rod contact member and electrical engagement of the rod and bore contact members. In the electrically engaged position, the stop ring and the gas sealing ring of the switch module are aligned with the other recess in the rod contact member thereby allowing the stop and gas sealing rings to relax.
