| DOUGLAS SNAP TERMINALS ELECTRICAL CONNECTIONS TERMINALS Are Fool Proof at the Start-- and improve with Vibration FIGURE 6 A typical junction block for a multiple of wire connections made by first connecting the spring chambers to a metal strip and then mounted on an insulated base. FIGURE 7 A comparison of sizes 8 and 60 ampere types. Spring chambers and wire terminals are made of Brass and Cadmium Plated. FIGURE 8 SECTION A-A MAGNIFIED The terminal sleeve is swedged firmly to solid or stranded wire by a machine leased to the users of Douglas Snap Terminals. Note the solid mass of wire in the magnified cross section. FIGURE 9 A method commonly used to make a contact behind a panel board. The illustration at the right is a spring chamber mounted side-wise used in places where insufficient space would not permit a vertical mounting. | ||
