Description
Specification

Bring your V3 trigger back to life

Version 3 gearboxes power a huge range of replicas, from AKs and G36s to AUGs, G3s and MP5s. When the trigger contacts wear out, you get misfires and a soft, unreliable trigger. The SHS V3 Trigger Switch is a robust replacement that restores clean, consistent electrical contact.

Made to handle the heat

The high temperature polymer body copes with the arcing and heat that destroy tired switches, so your rifle keeps cycling reliably through a full day of skirmishing.

Big reliability for small money

A trigger switch is one of the most cost-effective upgrades in airsoft. Fitting a fresh one during a service, or as part of a project build, removes a common cause of frustrating dead triggers on the firing line.

DIY or let the workshop handle it

Because it lives inside the gearbox, fitting suits intermediate techs. Prefer it done properly first time? Our Kent airsoft repair and Tech-It service can fit and test it. See more airsoft upgrade parts to finish your build.

Frequently asked questions

Which gearboxes does this fit?

It is designed for Version 3 AEG gearboxes, which cover AK, G36, AUG, G3, MP5 and many similar platforms. Confirm your replica uses a V3 gearbox before ordering.

Why replace the trigger switch?

Worn or burnt contacts cause misfires, dead triggers and inconsistent cycling. A fresh switch restores clean electrical flow for dependable semi and full auto.

Is fitting a beginner job?

It is an intermediate job. The gearbox has to come out and be opened, so it suits players comfortable with a basic strip, or those using a technician.

Will a MOSFET help it last longer?

Yes. A MOSFET greatly reduces the arcing that damages trigger contacts, which is well worth doing on higher-powered or high rate of fire V3 builds.

Can you fit it for me?

Absolutely. Our in-house Kent airsoft repair and Tech-It service can install the switch, test the gearbox and chronograph the rifle for you.
