No idea on the Ultrasonic cleaning but if you use a replacement 3 terminal switch such as the VW 3 terminal, many have reported they do not seem to last long.
The accepted 3 terminal replacement that gets good reviews is the commonly available and relatively inexpensive 2 terminal switch as used on conventional suspension cars along with a relay to provide the switching for the TL. The other switch getting good reviews is a mechanical switch mounted on a bracket to the steering column inside the car and operated by the brake pedal arm.
The relay and two terminal is easy to do and Dwight Heinmuller has kits for the mechanical option or you can build your own there too.
Here is a diagram showing one way to make an easy to build relay replacement and there are other versions with slightly different wiring. Also, a mechanical switch drawing for 56 models with the wide pedal arm to the left of the steering column. 55 models with the narrow arm on the right need a different bracket.
