GENERAL INFORMATION:
Barriers may be used with Snap-In Bezel Mounting Switches to
provide safer separation between switch caps, thereby minimizing
accidential actuation of the wrong switch. "End" and "center" barrier
are used if two or more switches are mounted in common hole cutout.
For individual switch mounting, two end barriers are used.
INSERTION:
The barriers are held to the side of the switch by hand and inserted
as one unit. The end or side barrier becomes captured upon insertion
into a panel and appear to be one complete assembly.
