Still Float Safety Switch | FMB / Union / Realstar 0315001

This still float safety switch, part 0315001, is used in the still/distillation level safety circuit on compatible FMB / Firbimatic, Union, and Realstar dry cleaning machines. The switch helps monitor the level condition in the still or distiller area and provides a safety/control signal so the machine can avoid unsafe still operation when the float signal or liquid level is not correct. Use this listing where the original machine record, installed component, and service manual match 0315001, old FMB / Firbimatic A5981, or C1400003.

Description, specifications, cross references, and fitment

This still float safety switch, part 0315001, is used in the still/distillation level safety circuit on compatible FMB / Firbimatic, Union, and Realstar dry cleaning machines.

The switch helps monitor the level condition in the still or distiller area and provides a safety/control signal so the machine can avoid unsafe still operation when the float signal or liquid level is not correct.

Use this listing where the original machine record, installed component, and service manual match 0315001, old FMB / Firbimatic A5981, or C1400003. Before ordering, compare the installed switch, float/rod assembly, wiring, mounting, and manual table reference.

Technical Specifications

  • Component type: still/distiller level safety float switch.

  • Service function: float-operated level safety/control signal for the still or distillation section.

  • Common listing description: Still Level Safety Float Switch.

  • Additional manual/price-list wording: Still Float Switch, Still Float, Floating Level Control, and Interruttore a Galleggiante.

  • Primary FMB / Firbimatic part reference: 0315001.

  • Legacy FMB / Firbimatic reference: A5981.

  • Component/reference number found with this listing: C1400003.

  • Manual table context: 4-CEL 0315001. Related rod/float assembly reference 2-ASTA 40A763/PGT may help physical verification, but must be checked against the installed assembly before ordering.

  • Do not substitute nearby level/float references such as 0315008, 0315013, 0315014, 0315015, 0315017, or 0315018 unless the machine manual and installed component confirm the match.

Part Numbers & Cross References

Use this section to separate direct part numbers from cross-reference and verification notes. Always confirm the installed component, machine manual, still/distiller location, wiring, mounting, and physical float/rod arrangement before ordering.

Ordering Verification

Confirm the installed part number, legacy A5981 reference, C1400003 reference, visible component markings, physical float/rod arrangement, wiring, connector style, mounting, and still/distiller location before ordering.

Match the machine data plate and service manual table against the installed switch. This listing is for the still float safety switch / floating level control, not the other nearby short/long float switches or preseparator level controls.

For FMB / Firbimatic, Union, and Realstar machines, compare photos of the installed component and the manual exploded-view/table reference. Contact Corbett Equipment if you need help verifying the correct switch before ordering.
