The float is a chemical
resistant polypropylene casing with a firmly bonded electrical cable protruding.
One end of the cable is permanently connected to the enclosed mercury switch
and the entire assembly is encapsulated to form a completely water tight and
impact resistant unit. Type S - Suspended has built in weight.
