Balboa air button

This air button, manufactured by Balboa, can turn on or off a device (like a pump, a blower or a light fitting). It works with air tubing and is compatible with all the air switches available from tubs.

This mechanical system is old-fashioned but inexpensive. Most modern spas use low-voltage digital controls.
