• respective upper and lower contact holders each having a pair of mounts flanking the rod and respectively downwardly and upwardly engaging the limbs of the contact, the mounts of the upper contact holder being formed with bores aligned with the upper bore of the rod and with the upper bores of the respective limbs and the mounts of the lower contact holder being formed with bores aligned with the lower bore of the rod and with the lower bores of the respective limb;
• an upper pin extending through the bores of the mounts of the upper holder, the upper bores of the limbs, and the upper bore of the rod;
• and
• a lower pin extending through the bores of the mounts of the lower holder, the lower bores of the limbs, and the lower bore of the rod.
