7 Float Switch Assemblies Applications General Float switches are used to signal liquid level positions for alarm and All models listed are UL listed and CSA certified for use in water or sew- pump control applications.Orenco float switch assemblies can be age.Non-mercury float switches(models B,C,N,and P)are used where mounted in pump vaults,effluent screens, pump basins,and risers. components containing mercury are prohibited. Float switches are typically ordered in assemblies that include one or more switches mounted on a 1-inch PVC float stem.ABS float collars ! are used to provide secure mounting that is easily adjustable.
