Thanks for reaching out and we can get you a new automatic transfer switch to replace your Parallax 5070. That, like you said, is a 50 amp, 120V/240V rated transfer switch, and since these are interchangeable I would go with the manufacturer with the best quality, which is Progressive Dynamics:

- 50A Transfer Switch - Metal Box - 120V/240V AC # PD52

From what I was able to find on your Parallax 5070, it with its mounting bracket measured 11-1/4” long x 8-1/4” wide x 5-1/4” deep, and while you definitely want to verify that, the # PD52 is very similar, measuring 10-3/8" long x 6-7/8" wide x 4-1/2" tall.

So it won't have any issues fitting right in place and will work superbly for you.
