If you own a classic Jaguar E type/XKE than you're more than likely familiar with the temperamental fan switch or "Otter switch", and if you are, you're probably familiar with the painstaking task of finding a new, reputable product. At our shop we recently dealt with this problem. So we decided to make our own and fit it with a 180 degree Fahrenheit switch to kick on those fans before any overheating is possible and turns off at a cool 160 degrees Fahrenheit. The plate is made with the exact specs from the stock switch plate so there will be no fitment issues and your holes will line up perfectly.
