Frequently Asked Questions

Q: What appliances is this pneumatic push button switch compatible with?

A: This pneumatic air switch is designed for use with garbage disposals, spa bathtubs, massage tubs, children's water toy systems, and other appliances that use a pneumatic (air-actuated) on/off switch. It supports 125V–250V at up to 16A, making it suitable for most standard household appliances in this category.

Q: What is the difference between the three hole sizes (28mm, 32mm, 34mm)?

A: The switch is available in three different installation hole diameters — 28mm, 32mm, and 34mm — to fit the pre-drilled hole in your sink, countertop, or bathtub deck. Measure your existing installation hole or check your appliance's manual to select the correct size before ordering.

Q: Is this switch safe to use near water?

A: Yes. Because it is a pneumatic (air-activated) switch, there is no direct electrical connection at the button itself. Air pressure transmits the signal to the control unit, which keeps the button assembly safe for wet environments like spa tubs and kitchen sinks. The silica gel gasket also provides a water-resistant seal around the installation hole.

Q: Does this package include the full switch set or just the button?

A: You can choose from two options: (A) the SPA bath switch button only, or (B) a complete SPA bath switch set. Please select the appropriate option when adding the product to your cart.
