## Switch Operation 

Depending on the mounting position, the float on these switches can rise or lower with the liquid level. By rotating the switch 180°, the switch operation can be Normally Open or Normally Closed (except Type 12). 

FLOAT PIVOTS STAY ABOVE WATER Type 12 – N.C. “Drop Float” Design WATER MAGNET N.C. ACTUATION RANGE 25˝ to .50˝ ; 4 | ~~S~~ S 45/64˝ REF. The LS-7 Type 12 is ideal for use on food warmers, hot water heaters, steam cookers, small boilers or wherever water evaporation occurs. The switch is used effectively for either high fluid level alarms or >. Food  Warmer water make up systems. The units are made of Norylwhich carries NSF approval for use in potable water,[®] , =, and are supplied with FDA-approved Buna gaskets.
