One of the most popular items in this category has to be these PTO in dash switches. These switches over the years get rain in them and they are out in all kinds of weather. After being in service for many years, rust and corrosion take em' out. These switches are limited, and when they're gone, they're gone! Duplicate of the original with 4 blades. 
 
NOTE: The manufacturer is not sending hardware with these switches anymore so save your attaching hardware. Why this is, we don't know, but to us its like buying shoes with no laces. Save your attaching hardware!
