FAQs
Is this an electrical switch?
No — it’s an air actuator. Pressing the button moves air through tubing to a remote pneumatic switch element which makes/breaks the electrical contacts away from the wet area.
Does it come with tubing?
Tubing is not included. Use compatible pneumatic tubing sized for your switch element (commonly small-bore PVC).
Can I mount it on a bath or spa?
Yes — this style is chosen for wet environments because it provides electrical isolation at the point of actuation. Always follow local regulations and manufacturer guidance.
