I have a 05 Roadster, I need to replace the micro switch on top of my windshield so that the top functions properly. Help ! They seem to no longer exist. Is there another vehicle that uses the same switch or a resource that I haven't found to purchase one ?

 

All I can suggest is keeping an eye on Ebay and putting it up and down manually.

 

Thousands of microswitch configurations are available from numerous manufacturers. I recommend that you define what you need: Is the switch normally open or closed? What are the dimensions of the failed switch, and the size & location of its mounting holes? What is the length & shape of the actuating lever?
When you have these characteristics defined, start looking at what's available and purchase one or (hopefully) more candidates; discover what works well, and do us all a favor by reporting your results. The few words I have used here don't describe the hours you'll spend finding a suitable switch, and I hope you don't get discouraged and give up.

Good Luck!

 

Plus one on that thought. Many, maybe I should most of these parts have the makers name and number on them. Some have the Mercedes number as well. These incidental items are purchased off the shelf and these switches will be to an industry standard and interchangeable with the same parts made by other companies. If they had been made specifically for the Crossfire they would be extremely expensive.
