Abstract
Electrical circuitry for preventing or substantially reducing electrical arcing at the muzzle of an electromagnetic projectile launcher. The circuitry provides a plurality of switches which interconnect portions of the rails of the launcher so that a unidirectional current flows through, the armature of the launcher is a first direction when the armature is in a first section of the launcher and a second section of the launcher. The switches, also cause a current, in a direction opposite the direction of the first direction, to flow through the armature of the launcher when the armature is in the second section of the launcher.
