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
