Whilst particular types of float switch have been developed to limit the effects of this build up, the experience and knowledge of the switch manufacturer is also critical here.It is critical to select a float switch that is constructed from the right materials that are compatible with the liquids and temperatures of the particular application. Component damage as a result of incorrect materials selection can ultimately cause failure of a float switch, which may have severe consequences. These tables provide a good indication of the suitability of the various float switch materials in a wide range of liquids.
