SEBO Mechanical Switch and Coupling for 300 and 350 Uprights

On the mechanical 300 and 350 uprights the control the operator touches does not act on the switch directly. A coupling carries that movement across to the switch body, and because the two wear as a pair they are supplied together as one assembly under part 05112WI. Fitting a switch alone leaves the new component working through the same tired linkage that caused the fault.

A worn coupling announces itself as a control that feels vague. The machine takes two pushes to start, the switch stops clicking over cleanly, or power drops out when the handle is moved through its travel. None of that is a wiring fault, and chasing it through the cord and the motor wastes an afternoon. Renewing switch and coupling together gives back a positive, repeatable action with a definite click at each end of the throw.

• Part number: 05112WI
• Fitment: SEBO Mechanical 300 and 350 upright vacuums
• Assembly: switch together with its operating coupling
• Job: passes handle movement into the switch body so motor and power respond to it
• Corrects: intermittent, vague or unresponsive on and off action
• Sold: individually as a complete assembly

Unplug the vacuum before starting and note how the original coupling sits in the housing, including which way round it faces, before taking it out. Fitting the replacement in the same orientation is the whole of the job. The screws that hold this area of the machine together are ordinary SEBO service hardware, so keep them laid out in the order they come off.

Search terms that lead here include SEBO 300 switch replacement, SEBO 350 mechanical switch coupling and genuine SEBO 05112WI. Confirm from the data plate that the machine is a mechanical 300 or 350 rather than an electronic model before ordering, since the control arrangement differs.
