FYI.

I have been working with a guy, that makes microswitch triggers for P90 and FN2000 AEG’s, to make a microswitch trigger version for Thompson AEG’s/ Pulse Rifles. We are getting close to testing the prototype out on a working Thompson, probably in the next month or so.

This upgrade should help improve trigger responsiveness over the old trigger contacts set up, and when combined with a mosfet, and a good AEG motor, bring our AEGs the same kind of snappy trigger responsiveness and positive feel as current, top of the line AEGs do, today.

I will let everyone know how it goes, and if everything is good, post the source of supply!

Got a price point?

What about the mg42 replicas evike sells?

Interesting / interested.

@K_Joker: the LCT M60-001 Replacement Trigger Switch Assembly might be a substitute, if you're needing one ...

Just got an email from the guy making the microswitch trigger unit. He sent me a video and a few pictures, showing the new microswitch trigger in action, it looks really good. He is about to ship me the prototype switch back for me to try out and run it through the paces.

I am going to confirm with him but it appears, at this stage it may need to be a 1:1 trade, so he can use the “trigger” piece that the finger pulls to fire the gun, unless there can be a source found for the unique peices that cant be fabricated.

Should be getting pics and a video of the prototype up soon, and the update y’all on the progress.

The switch is in the prototype stage , and we are about to test it in the field. I am hoping that we can knock it out of the park on the first swing but we shall see.

I am not sure how similar the MG42 trigger assembly is to the Thomspons, he would to the very least need a gearbox with trigger and motor, in order to design and test the switch.

I will be willing to buy the second prototype and report back on testing and install. We can discuss that further in the px section at whatever point you are ready for that.

And once I get further along in my budget savings plan I can see about direct shipping an mg42 gearbox assembly to you. The buggers are notorious for burning out as the drum in them holds 2000 6mm bb's...

The thing that gets me is we still have not perfected a case-less bullet as of yet as the heat issues cause premature firing on extended fires. The closest we can come at this point is a rail gun regarding what we saw in the movie. And in all actuality with some much beefier gearboxes, we could actually achieve a very close movie weapon with just bb's...

I know the price point in the P90 and FN2000 is around $40.00 USD, presuming around that price point.

He also carries mosfets, and can prewire them on the trigger for an extra cost.

I have a link of the video on Facebook, not sure if its viewable to all:

https://m.facebook.com/100028450740950/ ... dp=1&mdf=1

Please note that I am not the representative of the person doing the work, so I cant speak for him on any work you are interested in having him do. When he is ready to make a production item out of the microswitch/ or not, I will forward contact info, or even see if he is willing to come over here for a few posts.

As fat as caseless ammo, I am not sure what are are talking about, real steel? This post inst about real steel.

The AEG assembly for the mg42 is about 200 USD. There are no real aftermarket alternatives. The same could have been said about the Thompson Maraui until you.

Caseless ammo is what they used in the science fiction universe. In our case we are using plastic bb's. In a real to life comparison if we can amp up the FPS to about 2000 you would power comparable to a real bullet.

I tend to ramble a bit if I do not have sufficient caffeine in my system, so apologies for that. My mind tends to go in 20 directions all the time all at the same time and I am usually chewing on three different problems at the same time at any given point.

I recieved the microswitch yesterday, so far looks good. I need to break the lower down and wire it in.

Its set up for direct mosfet install, trigger wired to (Gate dual wire) mosfet, power/mosfet to motor.

Let us know how it works and how easy the install was.

I did receive the microswitch trigger but am having issues with it firing; I think I need to wile the programming on my Warfet, and do a fresh start on it.

As far as pictures, it looks almost exactly like a standard Thompson trigger, and installs the same. The main difference is the the Gate trigger wires go from the microswitch to the mosfet, and the battery wires go straight to the motor.

I ended up putting a M120 spring to get it to ~1.49J) in my Thompson that I tested the switch with, and put the standard trigger back, to take it to the airsoft field on Saturday, and with .30g bbs, I was the longest reaching, non DMR AEG on the field but I was using iron sights. Inside of 150 feet, I was wrecking shop with it. Half the guys that I played with want a Thompson now, especially after I let them shoot it.

I might just have leaked out the worlds worst kept secret on how good the Thompson platform is versus the M4 and others! :)

I figured out why the microswitch trigger wasn’t working; I had the Warfet set to “Stock Wired”, when I needed to have the setting for “Hard Wired” for the trigger.

The issues that are now needing to be overcome are that the wires need to be about 7 inches longer, and the selector plate isn’t able to stop the trigger from being able to be pulled.

More updates, as they come.

Update on the microswitch trigger.

I tested the microswitch trigger for a little bit, and the trigger response is good, the main issues needing to be looked at is that the wiring for the battery and mosfet are too short to make it through the stock, and that the selector plate wasnt blocking the trigger from moving when the safety was on.

I sent the builder an extra upper, lower, stock, pistol grip, and all of the selector plate pieces; so he can work out the last issues to a more skirmish-able piece. I’ll break down my pulse rifle to put the unit in, and take it to the field and run it through its paces. I will also do a test fit on both my plastic furnitured and wood furnitured Thompsons to ensure a good fit for them as well.

A brief update on the Thompson/Pulse Rifle microswitch trigger unit; the builder has been tied down with life and other work projects, so development is delayed a bit. He is hoping to have major progress by March 2021.

I really do believe that the trigger will help liven up Pulse Rifles and Thompson, make it much easier to integrate a full fledged mosfet (programmables), such as a Gate Warfet.

As progress is made, I will send updates.
