Replacing limit switch on old retractable awning

I’ve been contacted by the owners of a historic mansion who are looking to replace the limit switch on the motor of a very old retractable awning. The original awning was installed sometime between the 1940s and the 1960s; and at 45 inches, the awning is pretty large. I’ve already contacted Tri Vantage, since it was an Astrup system, and they’re looking into it for me. I also contacted General Motors, who made the original switch, and Somfy, but no luck so far. Any suggestions on where else we could look?

We sent out an SOS to the members of the Professional Awning Manufacturers Association (PAMA), asking for advice. In doing so, we found a supplier who looked at the photo provided and indicated that he thought the switch was a standard rotary switch, and that the type of switch used for heavy theatrical curtains might do the trick. His company may be able to supply it: Motion Control Systems.

If that doesn’t work out, we also had several other awning manufacturers suggest that you contact an electrical supply house or a motor repair company in your area. While they may be unfamiliar with awning motors, the part itself should be something they can supply, or find you an alternative. Many thanks to the members of PAMA for their assistance.
