SEBO On/Off Button Lens for Switched ET-1 and ET-2 Power Heads

Switched power heads carry a small moulded lens over the on/off control. Part 2957 is that piece: the face your thumb presses and the cover that keeps carpet dust away from the switch sitting behind it.

SEBO lists it at position 139 on the ET-1/ET-2 power head diagram, where it is noted as the left hand item, at 139 on the FELIX sheet and at 136 on the DART. Yellowing, a star crack across the face, or a lens that has popped out and vanished under the sofa are the reasons this part gets ordered. Because the lens is only a cover, it is worth confirming that the switch itself still operates cleanly while the head is open: the single pole switch is 05114, the lever and leaf spring behind it are 2958ER, and SEBO sells the whole switch group built up as 2959ER if the fault turns out to be electrical rather than cosmetic.

Unswitched heads have no lens to lose, so check which build you have before ordering a SEBO ET-1 on/off button lens. The brush light lens on the other side of the head is 2956, a different moulding at the next position along, and the two are easy to confuse when working from the drawing rather than the number.
