Very very happy

Installed and Working Fine (See review notes)
I used this to repair our old Jacuzzi tub that came with our house. A couple notes: 1) It doesn't come with a tube lock nut like the original pump equipment, but it doesn' actually need it. 2) The hole on the housing that the treaded side gets push though is set up for the original equipment that had 2 flat sides. So I drilled out the plastic cover a little bit so this new switch would fit through. I guess you could use a file or similar to make to flat sides ont he switch, but seemed like making the cover hole round was a better idea.

Worked great for the Jacuzzi Tub
I love my Jacuzzi tub and when it stopped working this was the fix. It was easy to change and has been working since installation 6+ months ago.

Worked on Kohler tub
This model worked for my kohler tub. I tried one of the other types and that switch would not work.

It worked
It worked on our Jacuzzi jetted tub. Would have been nice if the threaded connector was the same diameter as the OEM part. At least it did include a new nut to secure it to the housing. But the air hose nut did not fit. Air hose seems secure without the nut and hopefully will hold over time. Next day delivery was key to meet our contractor’s schedule, so couldn’t wait for a Jacuzzi part.

Better than the Jacuzzi OEM switch.
I used this switch to repair my Jacuzzi brand whirlpool tub. I chose this switch over the OEM as it had better rating and appears to be more serviceable. The original lasted about 1 year of very light duty. I hope this one will last longer. So far so good. Please note that to use this for a Jacuzzi brand tub you will have to over-size the mounting hole which is in a plastic body and took <2 seconds with a step bit. Best of luck.
