PolarStar V2 AEG Switchboard

PolarStar V2 AEG Switchboard

The PolarStar V2 AEG Switchboard provides a direct replacement for the original trigger switch in TM spec Version 2 gearboxes. It replaces the traditional trolley-style contact system with a dedicated electronic board. As a result, it delivers a cleaner and more reliable trigger signal for compatible HPA builds.

Furthermore, this switchboard supports PolarStar F2, F1, and JACK systems, which makes it suitable for both new builds and repairs. It also works with single-solenoid and dual-solenoid conversion kits, giving users flexibility across different setups. Therefore, it serves as a dependable solution when restoring or upgrading an existing HPA gearbox.

However, this board does not support all Version 2 designs. Specifically, it will not fit gearboxes that use snap-action or microswitch triggers, such as Ares V2 systems. In addition, it is not compatible with the PolarStar Fusion Engine, so correct system matching is essential before installation.

Moreover, PolarStar has clearly labelled each connection point to simplify installation. The board uses J1 for the main harness, J2 for the poppet solenoid, and J3 for the nozzle solenoid. For single-solenoid systems, you should connect to J2 only and leave J3 empty. As a result, wiring errors are reduced and installation becomes more straightforward.

Finally, this switchboard suits users who want a genuine PolarStar replacement part for a TM spec V2 gearbox shell. It restores proper trigger function while maintaining correct factory wiring standards. Therefore, it is an essential component for maintaining performance and reliability in compatible HPA builds.

If you are rebuilding or repairing a compatible V2 HPA setup, the PolarStar V2 Switchboard gives you a genuine replacement option that matches PolarStar’s intended wiring and gearbox fitment.
