Output
All switches are continuous rotation.
Dot indicates terminal to common
connection.
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.
Soldering information
*For the most current soldering & cleaning processing
guidelines, reference Grayhill Dip Switch Processing
Information, Bulletin 1234
Soldering temperature: 260° C maximum.
cleaning: Acceptable solutions include
1-1-1 Trichlorenthane, Freon (TF, TE, or
TMS), Isopropyl Alcohol and detergent
