Solved Installing new momentary pilot switches

[Andreas W]

I have bought 2x military momentary switches to replace my power & reset buttons to my case, but when I got the switches they do not exactly look like the guide I found from mnpctech, I ordered the switches from frozencpu so my question is where does the blue cable go, if I look at the switch I have them numbered 1,2,3 but there is just a hole at 2 that I cant really do anything with I assume. So would the blue cable go to 1 and white to 3? and would that be the same for reset also. I just dont want to break something if that is possible from wiring these wrong, and from the googling I did it seems that I need to buy female spade connectors is that correct?

You can solder the wires directly to the tags, so that wouldn't be a problem. Also, you cannot wire them incorrectly, providing that these are momentary contact switches (i.e. make when operated and break when released). Check to ensure that the switches operate as intended BEFORE using them for this purpose.

 

[Andreas W]

No idea how to solder or got the tool for it, and how would I be able to test that they work as they are suppose to? They do click back when I press them, like if I hold it and then press it up and I then let go of it the switch moves back to its original state or that was not what you meant?

I would strongly suggest that you at least go get yourself a pencil soldering iron at your local hobby or electronics store and practice using it on some spare wire...

If you're going to get into this kind of thing it's going to be an absolute requirement

Those lugs can be used with crimp connectors which you would have to also buy the connectors and tool for crimping them at the electronics or auto parts store...

I'd rather not mention the third option that requires no tools, it's just to ridiculous to even consider

 

[Andreas W]

Ah those crimp connectors you mentioned is the ones I mentioned as spade connectors, and I guess that would be the easiest thing to do. And I am not sure how much of these things I will be doing so it wont hurt to at least look that thing up. My biggest concern was that I would wire it wrong, but that don't seem to be possible so thats good news

Those are awfully small wires for solder free connectors. you'll be hard pressed to find a blade socket that big that will crimp down to a 22 Ga wire (or whatever size that is).

These should work, separate crimps for conductor and insulator.

Although a soldering iron is a better way to go, it's your choice.

This picture here has arrows pointing in both directions for on. Which would mean it should have two positions to "make" contact and complete the circuit before returning to the "break" or normally open position.

Seeing how this switch does not have 3 connectors, and it's normally open position is pointing down in this shot, it is not a make-break-make switch. (Or it is broken)

Like the one used here The Mod Brothers • View topic - Installing Momentary Fighter Pilot Switch for Power

If you notice in that link he also attaches the blue wire to the terminal that is in line with it's normally open position, in your case the bottom one in the picture above.

You can always test the switch with an Ohmeter to make sure it is working as it is supposed to. Actually that should be your first move.

 

[Andreas W]

I read that guide, hence why I am asking here since these looks different ^^, and I am only able to flip it 1 way then it goes back down, I supposed this is what it was suppose to do but if they seem to be broken I am not sure if I want to use them

Do you have an Ohmmeter?

I was just commenting on what I can see in the picture since I can't actually hold it.

 

[Andreas W]

I think my dad have one, could you maybe try to explain what I am suppose to look at if I try it with an Ohmeter, if they work are they suppose to give a short signal and then die out?, I am kinda bad at explaining since english is not my main language

No problem, if you connect an ohmmeter to the switch, you should get continuity or a beep when you move the switch to on, and nothing when it's off since the circuit will be open.

So to check yours just touch the leads to each terminal, if you don't get a beep it is in the normally open position, by moving the toggle to the other position you should get a beep or low resistance until you let go of it. (It wont die out it will stop pretty abruptly)

If that is what you get when checking then your switch is working.

Like I mentioned above when pointing to that other article, you probably want to follow the way the switch is wired. On your switches, what terminal is the bottom one in the picture I reposted of yours?

 

[Andreas W]

Hmm not sure what you mean with terminal but my guess is what direction its pointing or the metal flicks, the switches are at default at 3, and need to be pushed to 1, hopefully this is what you meant

Sorry I wasn't more clear but that is what I meant, you answered my question.

So if you connect the blue to 3 and the white to 1 you will be doing the same as the one in the article.

I would still make sure your switches are working correctly before hooking them up.

Ok, will write that down and then head over to my dad tomorrow, middle of the night about now ^^, so I will be back tomorrow and write if they worked as suppose

OK, get some sleep.

Ok a slight update my dad can't seem to find his so I would need to buy one. My question is would something in the link bellow work?

Velleman DVM830 Digital Multimeter with Transistor Test Velleman DVM830 DVM 830 DVM-830

Yes, that would work. Did you notice it was discontinued?

It now links to this, which would also work. Actually a little better too, it has a continuity buzzer, the one in your link didn't.

Velleman DVM850BL Digital Multimeter with Backlight Velleman DVM850BL DVM 850BL DVM-850BL

Are you getting it somewhere else? It says it's only $17.90 but all orders need to be a $50.00 minimum.

 

[Andreas W]

I found a shop here in Sweden that sells the 830, but was not sure if I should link that site since it was all in Swedish so found a different site that was in english ^^, But I will see if the shop have that one since they don't really seem to be that expensive and it can always be good to have one

Edit#1 The same shop that was selling the older version also have the newer one that you linked and it was not that much more expensive so I will grab that one instead

Good man, smart thinking there. You're right it is always good to have one.

 

[Andreas W]

So I thank all for the help I have gotten and I will go pick one up when I have the opportunity since there is no rush mainly also because I am not sure where I want the switches yet, and will mark this thread as solved. And then later on if the switches work as intended I will upload another picture in the "show your rig" thread
