Polypropylene or Nylon; conduit connection. Common Specifications Switch Rating*: SPST, 20VA Lead Wire Gauge: No. 22 AWG Mounting Attitude: Horizontal. RoHS: In compliance with EU-directive 2011/65/EC requirements for chemicals and substances. * See “Electrical Data” on Page X-5 for more information. Approvals Media Compatibility Material 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). When the switch is mounted so that the float rises with the liquid level, the switch is N.C. 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. Visit www.GemsSensors.com for most current information.
