SPECIFICATIONS
General-purpose EnclosureMeets NEMA standards for Type 1 general-purpose enclosure and Type $ weatherresistant (waterprool). The general-purposenclosure is intended for industrial applications indoors as well as for general use out.doors.
Watertight Enclosure
Meets NEMA standards for Type 4 watertight enclosure as well as Type 12 dust-tightThe watertight enclosure is suitable for usein wet locations as well as in dusty areas ofsteel and cement mills.Bronze Enclosure
Use bronze enclosure on ship docks andother shoreside areas for extra corrosionresistance.0rder bronze levers.Nonoverlapping Circuits
With nonoverlapping circuits, one circuitis opened before another is closed.(SeeFig.12.)
Overlapping Circuits
With overlapping circuits, one circuit isopened after another is closed. (See Fig. 12.)Maintained-contact Switches
Switch remains in one position until it ismoved to opposite position by the operatingdog. Forked levers required.Spring-return
Switch returns to midposition after trip.ping dog has pressed over lever.When used with spring-return, only oneof the four circuits (maximum)can be anormally open snap-action contact.Contacts Actuated Both Directions
Circuit or circuits will have a change instate when switch is activated in either direc.tion.
Standard Universal Contact Blocks
This contact block is the basic construction unit for IC limit switches as well as1C3012 master switches.(See Page 2-2 fordetails.)
Snap-action contact BlocksSnap-action contact blocks provide quickmake quick-break contacts for slow-novingapplications of 180-pm maximum. Withquick-make quick-break contacts, buringot contact tips resultng irom slow move.ment is eliminated.
