PULLTOUNLOCK OPTION
When ordering pull-to-unlock toggle listings (See page 8 for configurations), add the suffix letter shown in the chart on page 11 to the standard
toggle listing or the MS part number. For example, to order a 11TW17 pull-to-unlock toggle switch with the lever locked in the center position,
add the letter E (i.e., 11TW17E, MS27720271E)
