PolarStar V3 AEG Switchboard

PolarStar V2 AEG Switchboard

The PolarStar V3 AEG Switchboard is a genuine replacement trigger board designed for TM-spec Version 3 gearboxes running compatible PolarStar HPA conversion systems. It is made to replace the original trolley-style trigger switch, so it gives builders a purpose-built electronic interface for selected HPA setups. As a result, it is a smart upgrade or replacement part for users chasing a cleaner and more reliable V3 conversion layout.

This switchboard is compatible with single or dual solenoid cylinder conversion kits, including the PolarStar F2, F1, and JACK. However, it is not compatible with the PolarStar Fusion Engine. Just as importantly, it is also not suited to V3 gearboxes that use a snap-action or microswitch trigger design, such as Ares V3 gearboxes. Therefore, checking gearbox type before purchase is essential.

For installers, PolarStar clearly identifies the header layout on the board. J1 is the main harness, J2 is the poppet solenoid, and J3 is the nozzle solenoid. If you are fitting a single solenoid system, PolarStar states that it should plug into J2, while J3 remains empty. Consequently, this board is a practical choice for repairs, fresh builds, or HPA conversions where correct V3 fitment matters.

For V3 HPA builders who need the correct electronic trigger interface, the PolarStar V3 Switchboard is a genuine fitment-focused solution for compatible F2, F1, and JACK builds

The PolarStar V3 AEG Switchboard suits HPA builders who are converting a TM-spec V3 gearbox to a PolarStar electronic system. It is especially useful when replacing a worn trigger contact assembly, repairing an existing HPA setup, or finishing a fresh F2, F1, or JACK install. Because fitment is specific, it is best matched to standard trolley-switch V3 platforms rather than microswitch-based gearbox variants.
