NOS Ranco 55-00113 thermostat switch for the Thermo King AC system. I have this switch model in the underdash Frigiking face model for the W113 so at least we can determine it will fit those models. Check the photos for fitment to your model. This has a flat spot on the switch knob but it’s shorter than another switch I have for the W108. Also the length of the threads are shorter. May affect how the knob sticks out. The 700 part number is Mercedes old system. They have been converted to 900 numbers. May not include the box shown as I had more than 1. Information as to what models this would work on is very difficult to obtain from the Classic center.
