It has appropriate control markings on the face of the panel to indicate the switch positions. It includes two card holders for tabulating the necess ary informatir n concerning the.antenna array. It comes in three types as follows: SA-1<strong>36</strong>/C.-This type includes the 20 posjtion switch AN Typ" SA-139 /IJ. Figure l-7. Switch Pqnel AN Type SA-138/G, Fronl View.

The constrtrction of all three tvpes is similar, the difference being in the nunlb:'r' of contacts provided. The 10 and 60 position srvitches consist of a rillzerr plated brass contact ring in which specially constructed coaxial silver plated contacts are arranged in two concentric circles, each circle containing half the total ntrrnirer (see figtrre 1-B). Each contact is slrrl'ounded by a poll'styrene instrlator rvhich is fitted into arl appropriate hole in the contact ring. A Connector Nil'i'\' Typ" -49191 screws into thc- bottorn of the contact ring to rnat€' with the silver contac:ts. The contacts protrtrcle slightl'v riirove the plane of the contact ring. The rotor of the switch consists of an arm ftttecl q with specially designed RF spring loaded coaxial fittings on each end which make contact with the colr- ;, tacts in the contact ring. The arms are of different 'ilengths so that one rnakes contact rvith the inner circle of contacts and the clther rnakes contact with the outer circle. The contacts in the contact ring are staggered so that one arrn is rnaking contact while the other is between the contacts. A suitable detent rnechanism is includecl which insures positive positioning of the rotor at the point of proper contact. The coaxial fittings on the encls of the rotor anns are connected in parallel to a coaxial fitting at the exact center of rotation which serves as the output connection for the switch. The arm is grounded to the contact ring lry sliding brass contacts on either: end. The rotor is moturted on ball bearings which allow it to turn freely. The whole switch is enclosed in a cadrnium plated steel box of welded construction. The 20 position srvitch is sirnilar in construction except that the rotor has only one arm and the contacts al'e spaced in one circle on the contact ring. (6) IACK PANFTL AN I-i:) "-- [.rck Panerl AN Ty'p" oR,!6lliA[ TYPE I-239/C ( Figure I-239/C rnounts on the r RESTRICTED front of the cabinet and cclntains eleven Jack Switches Navy T,tp" CIA-49IBBB. It is normally used to distribute IIF signals from Jack Panel AN Typ" I-238/G to the station receivers and,/ or multi-couplers and auxiliarv ecluipment. It is a srze A panel. (C,.) RF JACK SWITCH NAVY TYPE CIA. 49I3BB (Figure 1-10).-The rear of each RF Jack Switch is eqtripped with trvo coaxial cable connectors, Navy Typ" -49f91. The design of the Jack Switch is such that when no patchcord plug is inserted into the front receptacle (Navy Typ" -19L20) the two rear connectors in the Jack Switch are bridged together with a sliding silver alloy contact. The received signal is therefore applied to a receiver or multicotrpler. When a Navy Typ" -4912fA patchcord plug is inserted in the front receptacle, the upper rear connector (antenna input) is disconnected from the circuit and the lower rear connector (receiver input) is connected with the inserted plug. This enables the operator to disconnect the receiver from the nonnal antenna and by patchcord connect another antenna to receiver.
