Electrical probe containing a capacitor and a switch assembly for selectively short circuiting such capacitor

Claim 1

AN ELECTRICAL PROBE AND SWITCH ASSEMBLY, COMPRISING: A HOLOW TABULAR PROBE BODY INCLUDING AN OUTER CONDUCTOR; A PROBE TIP INCLUDING A FIRST INNER CONDUCTOR, SECURED TO ONE END OF SAID PROBE BODY SO TAHT SAID FIRST INNER CONDUCTOR IS INSULATED FROM SAID OUTER CONDUCTOR; A CYLINDRICAL CAPACITOR MOUNTED ON SAID PROBE TIP INSIDE SAID PROBE BODY AND HAVING A PAIR OF OPPOSITE END TERMINALS SEPARATED BY A SOLID DIELECTRIC PORTION WITH THE INPUT TERMINAL ELECTRICALLY CONNECTED TO SAID FIRST INNER CONDUCTOR; A SECOND INNER CONDUCTOR MOUNTED IN SPACED INSULATED RELATIONSHIP WITHIN SAID OUTER CONDUCTOR AND ELECTROCALLY CONNECTED TO THE OUTPUT TERMINAL OF SAID CAPACITOR; SWITCH MEANS INCLUDING A PLURALITY OF MOVABLE CONTACTS EQUIDISTANTLY SPACED ABOUT THE CAPACITOR AND MOUNTED FOR LONGITUDINAL SLIDING MOVEMENT ON THE OUTER SURFACE OF THE DIELECTRIC PORTION OF SAID CAPACITOR INTO AND OUT OF ENGAGEMENT WITH AT LEAST ONE OF TERMINALS OF SAID ENGAGEMENT WITH AT LEAST CUIT THE TREMINALS OF SAID CAPACITOR; AND KNOB MEANS MOUNTED FOR LONGITUDINAL SLIDING MOVEMENT ON THE OUTER SURFACE OF SAID PROBE BODY AND CONNECTED TO SAID SWITCH CONTACTS INSIDE SAID PROBE BODY FOR SLIDING SAID SWITCH CONTACTS ALONG THE SURFACE OF SAID CAPACITOR BETWEEN AN A.C. SWITCH POSITION IN WHICH SAID CAPACITOR IS EFFECTIVELY CONNECTED IN SERIES WITH SAID INNER CONDUCTOR AND A D.C. SWITCH POSITION IN WHICH SAID CAPACITOR IS HORT-CIRCUITED BY SAID SWITCH CONTACTS.
