CODE OUTPUT CODE OUTPUT 1 2 4 8 1 2 4 8 Complement Output 0 1 2 3 4 5 6 7 8 9 A B C D E F Dot indicates terminal to common connection. All switches are continuous rotation. Octal and Octal Complement outputs are 0 thru 7 positions. BCD and BCD Complement outputs are 0 thru 9 positions. Hexadecimal and Hexadecimal Complement outputs are 0 thru F positions. Standard codes have natural color rotors; complements have rotors in a contrasting color. Internal O-ring: Rubber BUNA-N Soldering Information Soldering Temperature: 260° C maximum. Cleaning: Acceptable solutions include 1-1-1 Trichlorenthane, Freon (TF, TE, or TMS), Isopropyl Alcohol and detergent (140°F maximum). Solutions which are not recommended include Acetone, Methylene Chloride, and Freon TMC.
