Dual micro switch circuit that resets when one is released.

Ok terrible title, hard to shorten lol.

I need a circuit for an Airsoft gun that nobody makes!

Basically the way an Airsoft gun fires by semi auto is that when you pull the trigger the contacts close and send power. The gearbox does 1 rotation and a cam on one of the gears hits a lever that disconnects the contacts. When you release the trigger it drops back to its original position and then you can pull it again.

 

Now I want a remote trigger. That obviously cannot interact with the cut off lever as its not in the same location. So I plan to use 2 micro switches. 1 at the trigger point. That closes when the trigger is pulled. And another that is always closed until the cut off lever opens it for a brief second on its rotation. 

Now that's all simple enough. However. As soon as the lever stops acting upon the switch the circuit will go live again if the trigger is still held. And this in where lies my issues. 

I want the circuit to only reset and become live again (despite the second switch now closing) only when the trigger switch is released and pressed again. 

So I need some kind of current sense/logic switch to detect this. And this is where my knowledge runs out. So any input and help would be amazing. 

 

TLDR: 2 switch circuit, one always closed only opens for brief second. Second switch activates circuit. Need circuit to remain off until 1st switch is released and pressed again.

This behavior could be easily programmed into an arduino board if you can't find a pure hardware solution.

Don't ask to ask, just ask... please 🤨

Sauron'stm Product Scores:

Spoiler

Just a list of my personal scores for some products, in no particular order, with brief comments. I just got the idea to do them so they aren't many for now :)

Don't take these as complete reviews or final truths - they are just my personal impressions on products I may or may not have used, summed up in a couple of sentences and a rough score. All scores take into account the unit's price and time of release, heavily so, therefore don't expect absolute performance to be reflected here.

 

-Lenovo Thinkpad X220 - [8/10]

Spoiler

A durable and reliable machine that is relatively lightweight, has all the hardware it needs to never feel sluggish and has a great IPS matte screen. Downsides are mostly due to its age, most notably the screen resolution of 1366x768 and usb 2.0 ports.

 

-Apple Macbook (2015) - [Garbage -/10]

Spoiler

From my perspective, this product has no redeeming factors given its price and the competition. It is underpowered, overpriced, impractical due to its single port and is made redundant even by Apple's own iPad pro line.

 

-OnePlus X - [7/10]

Spoiler

A good phone for the price. It does everything I (and most people) need without being sluggish and has no particularly bad flaws. The lack of recent software updates and relatively barebones feature kit (most notably the lack of 5GHz wifi, biometric sensors and backlight for the capacitive buttons) prevent it from being exceptional.

 

-Microsoft Surface Book 2 - [Garbage - -/10]

Spoiler

Overpriced and rushed, offers nothing notable compared to the competition, doesn't come with an adequate charger despite the premium price. Worse than the Macbook for not even offering the small plus sides of having macOS. Buy a Razer Blade if you want high performance in a (relatively) light package.

 

-Intel Core i7 2600/k - [9/10]

Spoiler

Quite possibly Intel's best product launch ever. It had all the bleeding edge features of the time, it came with a very significant performance improvement over its predecessor and it had a soldered heatspreader, allowing for efficient cooling and great overclocking. Even the "locked" version could be overclocked through the multiplier within (quite reasonable) limits.

 

-Apple iPad Pro - [5/10]

Spoiler

A pretty good product, sunk by its price (plus the extra cost of the physical keyboard and the pencil). Buy it if you don't mind the Apple tax and are looking for a very light office machine with an excellent digitizer. Particularly good for rich students. Bad for cheap tinkerers like myself.

Pretend I'm an idiot lol and explain of possible what is need. I know what Arduino boards are. But I also know there's a million and one modules and thingies that connect to them. 

I know pcs and car mechanics. Not this electronic gibberish 😂

Relay logic wise I can sort of see what you want, I feel like drawing this out as ladder logic would help, not sure if you’re familiar

Afraid not. My electronics knowledge goes as far as 1980s and earlier cars..! So simple and basic!

No need for extra modules, the basic outputs on an arduino nano board should be enough for what you need. There are many guides you can find that convey a lot more than I could in a forum post.

Would be overly complex trying to use a logic-based solution, and seeing as you need an Arduino or similar for the whole remote trigger part, I'd just use that.

Well by remote I meant further down the gun. It's a bullpop! Not as in remote firing

I see.

 

I'm not quite sure I understand your explanation of what you want it to do. Can you maybe draw a diagram and/or write a truth table?
