This a New, Old Stock, variable speed motor control for a Pearl whirlpool bath, circa 1985-1995.

This button also has a timer function and a temperature display.

Pearl Baths at this time was an independent company out of Minneapolis, MN.

This button was used on their baths that utilized a ITT Marlow Geminii Plus variable speed pump whose model number started with "R" and also contained a "VS"

This same system of button and pump was used by other bath manufacturers such as Ameribath, Aqua Glass, Cielo, Oasis and Swirl-Way, the only difference being the decal/branding. (the last 3 photos show examples of other versions but the only one being offered is the Pearl  Bath in the first photo.

This is last one I have, maybe the last anywhere since they were discontinued over 25 years ago.

If you have one of these control/pump system and need a new button your only other option is to completely replace the system, requiring re-plumbing the new pump, or a new tub.

It''s new, only removed from bag to test and confirm operation.

This must be installed by a qualified service agent.

Be sure this is the part you need as there are no returns on electrical parts. There is plenty of info out there to research.
