Compatible with air spring activated systems for motorcycle suspension and pneumatic adjustable seats in cars and trucks. A relay (not included) may be required to deactivate the compressor. Pneumatic control: This switch is pneumatic. Verify the plug type of your original switch before purchase to ensure compatibility. Working principle: The air spring activation switch is integrated into a manual paddle valve. Operating the paddle up or down controls the compressor relay, regulating airflow from the air tank or compressor to the air bag or pneumatic seat device. Average air bag fill time is 8–12 seconds. High-quality material: The spring trigger switch is constructed from ABS material with a refined surface finish for extended service life, enhanced durability, and reliable performance.
