Soldered Seat ref#29562 Mercedes Switch Rebuild

YOU FOUND IT!! Forward & Back Center Lever: Rebuild your Mercedes W126 electric Seat Adjuster switches with this Reinforced replacement part. This is the center lever which holds the seat knob on. You can see the detailed retainers on the shaft that give a nice Snap-Fit!. This improved design offers a stronger shaft, and more material in stress zones. Best of all, you can leave the switch in the door and NOT have to solder anything! ;-) Just keep the springs and metal contacts from inside the current switch. Then easily drill-out the holes in the new 3D printed part, since holes are more accurate this way. The holes in this 3D part are slightly smaller than your final inside diameter for best fit. Then reassemble the switch, and you just saved the ~$400 of a new OEM part and all that annoying soldering of all those wires! See the complete How-To on the MB Forum and YouTube!
