Specialty Switches GEMS Excels in Switches for Special Requirements The products below are examples of the custom engineering GEMS can provide to meet specific application needs. These units are ideal for use in oils and water. LS-38760 Series - Cushioned Float LS-270 Series - Bracket Mounting Slosh Shield U.L. Recognized - File No. E45168 F Level monitoring and temperature switch in a single unit. Intermediate in size; single-setting temperature sensor is in bottom of stem. Cushioned float and switch for turbulent liquids or excessive vibration. Easily grounded. Ideal for tank trucks, construction equipment or mobile applications. Small, lightweight, and extremely stable in nonstatic, highly contaminated liquids. Slosh shielding minimizes effects of turbulence and helps prevent interference by foreign material. Bracket-mounted to any convenient surface.
