Product details
This OEM switch knob position ball (Part #A719-0000) fits Fuller Brush FBMMPWCF4 and Titan T4000.2 uprights. The small detent ball sits inside the switch knob mechanism, giving each setting a positive click and holding it in place.
Detent balls and their springs wear or go missing, and without one the switch knob feels loose, drifts between settings, or fails to hold a position. A vague, wandering switch makes the machine harder to control. Fitting the correct position ball restores a crisp, secure detent.
- Fits: Fuller Brush FBMMPWCF4; Titan T4000.2
- Function: OEM switch knob detent position ball
- Benefit: restores a positive click and firm setting hold
- Tip: work over a tray so the small ball is not lost during service
The ball seats into its detent pocket during a switch service. Verify your model before ordering to confirm the correct fit.
