"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. 22.35 [.880] 24.61 [.969] FOR USE WITH BEZEL SUFFIX 5/8" END BARRIER 5/8" CENTER BARRIER 3/4" END BARRIER 3/4" CENTER BARRIER 19.18 [.755] FIG 2 565 SERIES BARRIERS PART NO. 19.18 [.755] 21.44 [.844] 52.83 [2.080] MAX 565-0701 565-0711 565-0721 565-0731 12.70 ±.005 [.500±..13 FIG 1 52.83 [2.080] MAX ACCEPTS CAP SIZE Uses: T-1 3/4 MIDGET FLANGE BASE INCANDESCENT LAMP MOUNTING HOLE 15.88 [.625] SQ.
