The Ultimate Command Center for Your Air Suspension Seat
An air suspension seat compressor is only as reliable as the switch that controls it. If your current seat control paddle is leaking air, sticking, or failing to activate the pump, it’s time for an upgrade. This Premium 3-Position Pneumatic Paddle Switch provides precise, tactile control over your seat’s ride height, combining both electrical activation and air routing into one compact, heavy-duty unit.
Key Features & Engineering Excellence:
-
Integrated Electro-Pneumatic Control: Unlike standard switches, this paddle valve does two jobs at once. Pushing the paddle up closes the electrical circuit (turning on your compressor) while simultaneously opening the air valve to inflate the seat. Pushing it down opens the exhaust valve to release air into the cabin without engaging the electrical motor.
-
3-Position, 3-Way Center-Closed Design: The spring-loaded paddle automatically returns to the center “Normally Closed” position when released, locking the air pressure securely in the bladder to hold your perfect ride height.
-
Extreme Pressure Durability: Engineered to withstand a maximum pneumatic pressure of 1.5 MPa (Approx. 217 PSI), ensuring it will never blow out under the weight of a heavy driver hitting a massive pothole.
-
Universal Fit & Easy Installation: Features a standard snap-in design that fits seamlessly into 2.2mm – 3.2mm thick mounting panels. The air ports are equipped with quick-connect fittings designed for standard 6mm OD / 4mm ID air tubing.
-
Guaranteed Longevity: Tested for over 10,000 mechanical actuation cycles with a strict leakage tolerance of less than 10 ml/min.
Perfect Compatibility: Use this switch in conjunction with our heavy-duty Air Suspension Seat Compressors. It is the ideal replacement for broken control valves in commercial trucks (Freightliner, Volvo, Kenworth), agricultural tractors, heavy construction machinery, and luxury motorhomes.
