Abstract
A rotary switch for switching large direct currents is provided with a rotating cylinder having a pair of electrically connected angularly spaced conductors. Retractable sliding contacts are provided to make contact with the rotor surface and an insulated slot arc chamber is provided to improve the rate of voltage rise when the switch opens. Two of these switches can be connected in parallel to provide a switching system for an electromagnetic projectile launcher wherein one switch conducts initial charging current to charge an inductive storage device then commutates that current to the second switch which subsequently commutates the current to the launcher load.
