Airsoft MOSFET Power Switch Kit

1 reviews
0 5 5

Availability: Out of stock


Quick Overview

Protect trigger switch contacts from burning; May increase ROF by reducing resistance that the MOSFET puts into the circuit; Compatible with NiMH, LiPO and LiFE batteries Datasheet:P106a datasheet


The P106a has been developed to solve the problem of high currents burning out the trigger switch contacts. All the power is switched by a tiny, high power MOSFET device, with only a few mA going through the switch itself. This gives not only longer life to the trigger switch, but can also improve the rate of fire as the resistance that the MOSFET puts into the circuit is in many cases much less than that of the original switch. Compatible with NiMH, Lipo & LiFe batteries

Although we can repair most Action Electronics units, the sealed nature of this module means that it cannot be repaired.

Customer Reviews

In depth after action review. Review by Leewok
This is my video review.

Uk Action electronics Mosfet. Installed for its ease and simplicity.
Six wires all easily identified and paired off to perform their functions separate from each others looms and long enough to either front wire install or rear wire install.
16awg silicone wires for all currant handling wires and two thin signal wires.
This mosfet can take on heck of a beating I did a 60sec burst by accident and it lived, most other mosfets with out heat sink pop after a beating like that.

Over an AIRFET that I cant see for any other reasons other than saving less than pence sent out their fet with the shortest wires and a sticky back tab on one of the two identical wires to mark the battery. okay they had a clear instructions but the shortness of the wires meant Genuinely unnecessary work lengthening them to do the jobs they were intended to do sided with the slightly more confusing Loom AKA wiring with the T-off for the signal gave me the impression that it was very easy for even a extremely competent person to wire it wrongly.

I have no doubts about quality in the airfets or the Action electronics. however this one was much easier to install than the Airfet.
