PULL-TO-UNLOCK OPTION
When ordering pull-to-unlock toggle listings (see page 11 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)
