When switching to a Fusion Engine, you completely change philosophy. Gone is the classic mechanical contact… replaced by precise, responsive, and ultra-reliable electronic control.
The Polarstar V2 Switchboard for Fusion Engine Gen 3 is exactly that key component that replaces your original switch in a V2 gearbox. A clean, modern foundation, and above all essential to get the best out of your HPA setup.
A clean conversion for V2 gearboxes
This switchboard is designed to replace the standard mechanical contact found in Tokyo Marui–type V2 gearboxes.
The result:
👉 more precise trigger detection
👉 reduced mechanical wear
👉 significantly improved responsiveness
This is exactly what you expect when moving from a classic AEG to a high-end HPA system.
⚠️ Note: it is not compatible with gearboxes equipped with micro-switches (Ares, ATM, Shooter, etc.).
Dedicated compatibility for the Fusion Engine
This model is exclusively designed to work with the Fusion Engine system.
And this is important:
❌ not compatible with F2
❌ not compatible with F1
❌ not compatible with JACK
Each HPA system has its own specifics, and here we are clearly dealing with a component optimized for the Fusion Engine Gen 3.
Clear and efficient electronic control
The switchboard acts as a true hub between your trigger and the different components of your engine.
It features three main ports:
J1: main harness
J2: poppet solenoid
J3: nozzle solenoid
In practical terms? It centralizes information and ensures smooth communication between the key elements of your system.
The result: a clean, precise… and perfectly synchronized shot.
A real gain in reliability and feel
If you have ever played with a worn or unreliable mechanical contact, you know what we’re talking about…
With this switchboard, you switch to electronic detection:
more reliable over time
less sensitive to wear
more consistent in game
And honestly, you feel it immediately. The trigger becomes cleaner, sharper… almost “surgical.”
A discreet but essential component
It may look like just a simple electronic board. But in reality, it is what connects your action to your replica’s response.
Without a reliable switchboard, even the best HPA engine loses efficiency.
This is typically the kind of component you install to secure your setup… and play with peace of mind.
FAQ – V2 Switchboard for Fusion Engine Gen 3
What is a switchboard used for in HPA?
The switchboard replaces the mechanical contact of the gearbox and electronically detects trigger input to activate the HPA system.
Is this switchboard compatible with all HPA systems?
No. It is only compatible with the Fusion Engine Gen 3. It does not work with F1, F2, or JACK systems.
Can it be installed on any V2 gearbox?
It is compatible with standard Tokyo Marui–type V2 gearboxes. However, it does not fit models equipped with micro-switches (Ares, ATM, etc.).
What ports are available on this switchboard?
J1: main harness
J2: poppet solenoid
J3: nozzle solenoid
These ports allow connection of the different Fusion Engine components.
Does it improve performance?
Yes, especially in terms of responsiveness and reliability. Electronic detection is more precise and consistent than a mechanical contact.
Is it an important component in an HPA setup?
Yes, absolutely essential. It ensures transmission of the firing signal and coordination of internal components. Without it, the system cannot function properly.
