The Allen-Bradley 840-1BCE is the operator assembly for Bulletin 840 automatic float switches, converting liquid-level movement into switch action. It is specified for use with 840 switch styles B1, B4, B7, C1, C4, and C7, and includes a fixed stop collar and a fixed float at the end of the rod to set actuation. The assembly can be built with brass or stainless-steel components and is offered as a base-mounted option for tank or sump installations. This float operator assembly enables reliable, float-driven level sensing in industrial tanks, sumps, and other liquid-containment applications, where precise actuation at set levels is required.
