Single 10A air switch with three speed control for Spa Air Blowers fitted with series motors (with brushes/commutator only). No blower currently has built-in speeds. This is used to make those blowers have High/Medium/Low speeds. 

Do not connect induction motors such as pumps or major damage will result. May not work on blowers with a circuit board. These are suitable for direct-brushed motors only.

Each press of the air switch moves the air blower speed through High / Medium / Low / Off

Max load: 10A

Also replaces:

• Dega Airswitch Controllers
• Poolrite
• SpaceAge branded air switches
