• o r Data Sheet <br /> Float Switch Assemblies <br /> Applications General <br /> 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- <br /> pump control applications.Orenco float switch assemblies can be age.Non-mercury float switches(models B,C,N,and P)are used where <br /> mounted in pump vaults,effluent screens,pump basins,and risers. components containing mercury are prohibited. <br /> Float switches are typically ordered in assemblies that include one or <br /> more switches mounted on a 1-inch PVC float stem.ABS float col- <br /> lars are used to provide secure mounting that is easily adjustable."P" <br /> On ------------ Float collar and"N"model float switches use Super Vu-Tron®electrical cords for <br /> # X superior chemical and water resistance. <br /> c 1 <br /> E Standard Models <br /> � E Set paint - --®-- <br /> o B; C, G.
