• SPDT (single pole, double throw) switching, allowing control between two circuits or functions
• 20 amp rating, suitable for pumps, blowers, and other spa equipment
• Pneumatic operation, activated by an air button, keeping electrical components isolated from water
• Works with most standard spa air buttons and control systems
• Part no. 3-20-0006

Returns & installation: Confirm your spa uses a standard pneumatic air-button system before ordering, as electronic parts are non-returnable once installed. Installation should be performed with power disconnected, per your spa's service manual.
