American Standard Whirlpool Tub Air Actuator - AMS-753584-201

It is the air actuator button that sits on the tub deck and switches the whirlpool pump on and off. Pressing it sends a puff of air down a tube to the pump's air switch, so there is no electrical current at the button itself. American Standard part number 753584-201.0200A.

It is sold as the replacement air actuator for American Standard whirlpool tubs, so the right application is a like-for-like swap on an American Standard bath where the original white button has failed or cracked. Match the part number on the old actuator (753584-201.0200A) before ordering, since deck hole size and air tube fitting vary between tub series.

Not necessarily. On an air-actuated whirlpool the button, the air tube, and the air switch at the pump are separate pieces. If the pump runs when the switch is triggered directly, the fault is usually upstream and a new actuator like the American Standard 753584-201 handles it. If no air is moving at all, check the tube for a kink or water intrusion before buying anything else.

No wiring at the button. It is a pneumatic control, so it works on air pressure through a tube rather than low-voltage wire, which is why it can sit on a wet tub deck. The electrical connection stays at the pump.
