Seat Switch Parts and Repair - Breakage
My 1983 300SD has seat switch without memory.
Several good explanations on cleaning and fixing contacts for switches that stop working are already posted. My problem is the pins break that hold the button parts. When I go to the pick-a-part and junkyards I open the switches and just get the pins that the buttons attach to. On this car the switches do not have a connector on the back and cannot be simply unplugged and a replacement plugged in. So my question is, has anyone got a good answer to the plastic pins breaking ? I have repaired several with piano wire and resin, graphite tube, etc.. Now I am thinking that maybe I should just machine some out of aluminum or steel. Are these internal parts available anywhere ? Did MB ever improve on this ? Thanks all.

I had one door that had the soldered in switch and I got a kit from ************** that converted it to the plug in type. This was an easy project.
I don't know how much force you are putting on the switch levers but they shouldn't break that easily.

Personally, I know that the switches are to be used gently.
I can't convince the teenagers that sit in the passenger seat. I think that conversion kit is a good idea. And after studying pictures of the replacement switch it looks like the main pins are now metal and not plastic. For $275 I'll have a new , durable, seat switch. Thanks for the lead.
