Common Specifications Switch Rating*: SPST, 20VA Lead Wire Gauge: No. 22 AWG Mounting Attitude: Horizontal. * See “Electrical Data” on Page X-5 for more information. Approvals Material CE UL Recognized File No. E45168 cUL Recognized CSA Listed- File No. 30200 NSF Listed Mat. Std. 61 Nylon X X X X Polypropylene X X X X X Noryl® X X X X Versaplast™ X X X Food Warmer 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). Normally Open FLOAT ARC ENVELOPE Normally Closed When the switch is mounted so that the float lowers with the liquid level, the switch is N.O. When the switch is mounted so that the float rises with the liquid level, the switch is N.C. Types 3, 5, 7, 10 and 13 Type 12 – N.C. “Drop Float” Design 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 water make up systems. The units are made of Noryl®, which carries NSF approval for use in potable water, and are supplied with FDA-approved Buna gaskets.
