Rf shielded switch for safety-arming devices

Claim 1

A ROTARY SWITCH TO PROVIDE COMPLETE RF SHIELDING FOR THE ELECTRICAL INITIATOR COMPONENTS OF AN EXPLOSIVE TRAIN IN A WARHEAD SYSTEM FOR PREVENTING DELETERIOUS EFFECTS DUE TO ELECTROMAGNETIC RADIATION SOURCES IN THE VICINITY THEREOF; COMPRISING: (A) A METAL HOUSING MEMBER HAVING A CYLINDRICAL CAVITY THEREIN, (B) A METAL ROTOR ASSEMBLY ADAPTED TO FIT WITHIN SAID HOUSING CAVITY AND ROTATABLY MOUNTED THEREIN, (C) A METAL SHAFT AND DRIVE MEANS FOR ROTATING SAID ROTOR, (D) SAID HOUSING, ROTOR AND SHAFT MEANS ALL BEING IN METAL TO METAL CONTACT WITH EACH OTHER SO AS TO BE COMPLETELY RF CONDUCTIVE, (E) A PLURALITY OF EXPLOSIVE TRAIN COMPONENTS MOUNTED IN SAID HOUSING AND ROTOR, (F) AN ELECTRICAL INITIATOR HAVING TWO ELECTRICAL CONTACTS CONNECTED THERETO MOUNTED IN AN OFF-CENTER CAVITY IN SAID ROTOR, (G) A SPRING LOADED ELECTRICAL CONTACT ASSEMBLY WHICH IS CONNECTED TO AN EXTERNAL SOURCE OF ELECTRICAL ENERGY MOUNTED ADJACENT TO SAID ROTOR IN A PASSAGE IN SAID HOUSING, (H) AN RF SHIELDING CONDUCTIVE SPRING MEANS MOUNTED AT THE END OF SAID SPRING LOADED CONTACT ASSEMBLY ADJACENT TO SAID ROTOR AND BEING IN INTIMATE CONTACT THEREWITH, (I) SAID EXPLOSIVE TRAIN COMPONENTS, ELECTRICAL INITIATOR AND SPRING LOADED ELECTRICAL CONTACT ASSEMBLY BEING OUT-OF-LINE WHEN SAID ROTOR IS IN SAFE POSITION AND BEING IN-LINE WHEN SAID ROTOR IS ROTATED TO ARMED POSITION, WHEN IN SAID OUT-OF-LINE SAFE POSITION SAID RF CONDUCTIVE SPRING MEANS BEING IN CONTACT WITH BOTH SAID ROTOR AND SAID HOUSING THEREBY PREVENTING ANY RF ENERGY FROM REACHING THE ELECTRICAL INITIATOR IN SAID ROTOR, (J) SAID ELECTRICAL INITIATOR BEING COMPLETELY RF SHIELDED BY METAL COMPONENTS WHEN IN SAFE POSITION AND SUBSTANTIALLY SHIELDED WHEN IN ARMED POSITION.
