The Graco 16T646 Air Switch is a pneumatic control switch designed to regulate air flow for bead-gun and air-actuated functions. It detects trigger or bracket movement and opens or closes the air path accordingly. This ensures accurate activation of bead systems and other air-driven components within supported Graco equipment.
When installing, ensure the switch aligns properly with the trigger or bracket that engages the button. Connect the appropriate air line to the switch port, and test air function before using the machine for material application.
