SHS Trigger Contact Set for the Version 3 Gearbox — the Version 3 assembly, shaped for its own shell. Sold as a set.

Same job, different shell. This is the Version 3 trigger contact set, for gearboxes where the switch assembly sits and wires differently from a Version 2.

What fails is identical wherever you look. Arcing at the instant of contact slowly eats the surfaces, and a surface that is no longer flat no longer conducts cleanly.

You meet it as unreliability rather than as an outright failure, which is exactly why it tends to be diagnosed last. A set of contacts is a cheap thing to rule out early on.

Good to know before you buy

Reaching the gearbox on a Version 3 platform is often a longer job than on a Version 2, so put aside more time than the size of the part suggests.

Frequently asked questions

What causes contacts to fail?
Electrical arcing at the moment the circuit closes. It happens on every single pull, and it gets worse with a stiffer spring and a battery able to deliver more current.

Will a Version 2 set fit?
No. The assemblies are shaped for their own shell, even though the principle behind them is the same.

Should I fit a MOSFET instead?
A MOSFET moves the current away from the contacts and makes them last far longer. It is the better long-term answer, but it will not repair contacts that have already gone.

⚠ Check the version, not the platform: several very different-looking guns share a Version 3 gearbox and several similar-looking ones do not, so the shell is the only thing worth trusting here.
💡 Titan Forge Airsoft tip: Try a fresh battery before ordering. A tired pack produces symptoms that look remarkably like worn contacts. Browse gearbox parts.
