ORDERING INFORMATION

Switches are single deck, one pole switches of

2 to 10 positions. They have plastic or steel

shaft, with solder lug or PC terminals, with either

shorting or non-shorting contacts (plastic shaft

PC mount in non-shorting only). Ten position

switches have continuous rotation; fixed stop

switch with a metal shaft is available by special

order. Base part numbers are as follows:
