My Electrolux Epic 6500 SR will not turn off by pressing on the switch button. I took it apart and removed the switch assy. I can maunually turn it off & on by pressing the rocker arm on the switch assy. It appears that the problem is with the big blue operator button, not the switch assy itself. The button does not seem to press down enough to cause the rocker arm to switch. The button has a "U" shaped wire that presses on the rocker arm and it may have some broken plastic details at the base of the "U" wire. Right now I can use the vac by setting the switch to "on", reassembling the vac and pulling the power cord out to turn it off. Please let me know what part(s) to order to fix it.

WOW !!! Finally You are dead on, absolutely 100%.... good work!!!.

Get only a genuine new switch button with spring from an AERUS Electrolux dealer and reinstall.
Then carefully reassemble the entire body and wiring harness.
Congratulations getting there.... you rate as an honorary technical genius in my book,...Your wife should be bragging about you to her friends. I am genuinely impressed and I`ve been fixing these since 1990. I bow in your presence.
PS while youre in there, check the rocker for evidence of fatigue, it is the more common issue

I had the exact same issue. I replaced broken rocker switch, put everything back together what looks correctly, but the unit still will come on when plugged in and will not turn off. I was wondering whether the rocker should be in the "up" position or "down" when you reassemble the unit? And where does that rubber piece go? It looks like a thin three inch solid rubber tube, it was already out when I dissembled. Thank you for any pointers here.
