ACCESSORIES Non-Turn Washer Shaft and Panel Seal The Series 61 bushing is 3/8 inches in diameter and has a non-turn keyway to prevent rotation of the switch body when the panel is cut to fit. Another way to keep the switch from turning is to use a non-turn washer. The washer is brass, tin/zinc plated. Part number: 12C1087-1 Part number: SHH694-11, 302-2B stainless steel, no plating For shaft and panel seal version, the shaft is sealed by an o-ring inside the bushing. The panel is sealed by a flat gasket .045" thick at the base of the bushing. The panel seals will increase the behind panel dimension by .020" to .040", when the switch is mounted. The panel seal is silicon rubber. DIMENSIONS In inches (and millimeters) .625 ± .010 DIA.
