Description
Guarder Buttstock Switch Assembly (GE-07-21)
This is a Guarder switch assembly, part code GE-07-21, named as a buttstock switch assembly. A switch assembly is the trigger contact unit and its wiring inside an AEG gearbox: when the trigger is pulled, the contacts close and send power from the battery to the motor. The buttstock version is, as its name suggests, wired for rifles that carry the battery in the stock.
Guarder is a well-known maker of airsoft upgrade and replacement parts, and makes switch assemblies for several AEG types. Trigger contacts wear in normal use, so a switch assembly is one of the most common electrical repairs in an AEG.
Signs it needs replacing
Burnt, pitted or worn contacts cause a sluggish or unreliable trigger, a rifle that only fires sometimes, or one that stops firing altogether. Damaged wires or a melted switch housing are also signs that it is time for a new assembly.
Which rifle models this assembly fits is not stated in our listing, so please check the product photos and compare it with your existing switch before ordering, or contact us with your rifle details.
Fitting
Fitting a switch assembly means opening the gearbox and routing the wiring to the battery position, so it is best done by someone comfortable with AEG internals. Remove the battery first, note how the existing wiring is routed and take photos as you strip the gearbox.

Compatibility
Named for buttstock-wired AEGs. Switch assemblies differ between gearbox versions and makers, so compare with your existing switch and check your gearbox version before ordering. Guarder lists separate switch assemblies for other rifle types.
Care and maintenance
Use the correct grease sparingly on moving parts inside the gearbox and keep it off electrical contacts. Remove the battery whenever the rifle is not in use.
Use a battery and motor combination suitable for your rifle, as excessive current and heat speed up wear on switches and contacts. If you run a high-voltage LiPo battery, consider fitting a MOSFET.
Who is it for?
It is for AEG owners and techs replacing a worn trigger switch in a buttstock-wired rifle.
Please note: Battery and rifle are not included. Gearbox work is needed to fit this part.
