Korry 389 and 427/428 5/8-Inch Switches:
Individual Product Features (IPF) File Library
The interactive Individual Product Features (IPF) files provided below are MS-Word forms that allow you to specify a Quick Switch
configuration exactly suited to your application. Once you have selected the most applicable IPF file, you will need to customize it
through its embedded drop-down menus and text boxes.
The IPF files have been constructed for predetermined sets of features, so that some drop-down menus will allow only one choice. Drop-down
menus for switch action type, legend configuration data, and photometric requirements have multiple options. The IPF files also
require special configuration data to be added to text boxes (filled in by default with "TBD").
Make sure the MS-Word document lock command has been enabled and is located in your quick access tool bar. The drop-down menus will not work if the
document is not locked. Go to the "Review" tab and click on "Restrict Editing" to enable lock command.
For specific instructions on how to configure IPF files, please consult this guide:
