Title: .187" vs .250" female quick-disconnects
Post by: Dan on March 11, 2002, 02:44:19 pm
I'm almost ready to wire up my first interchangeable control panel and was wondering if it's a bad idea to use .250" female qd's instead of .187" size because I already have a whole box full of the .250" size.

Thanks,
Dan

If you're just using them to connect to your joysticks and buttons, the .187 are the ones that fit.  I don't know how likely it is that the .25 will slip off, but if you've got the parts, just try them out.

If you're using them as panel-to-cabinet connections, you can use whatever you want.  Just get some male .25 connects and you'll be set.

Cherry microswitches use the .187 connectors, The .250 connectors might slip off because only one side of the connector will actually be holding on.

You could use them as a temporary measure, but to make the best possible connection get the .187 ones. For what they are worth money wise, you will be saving alot on more headack piles...

I did that on my first project and they kept falling off.  My first project was just a control panel and I didn't have access to fix it without a TON of work.  I got so PISSED OFF that I finally bought an arcade machine and did it right..

so it's a great idea if you want to scrap your current project and do a bigger one :)

they are like 4 bucks for 100, get the right ones and you wont be sorry

What's to figure out? Slip your wire in the cylindrical end, crimp it nice and tight with a crimping tool, and slide it onto the male disconnect on the microswitch. Make sure you connect to the COM (common) connect for ground and the NO (normally open) connect for the switch. Don't use the NC (normally closed) connect.

BTW, "quick connect", "connect", and "disconnect" are all synonyms. The actual thingamabobs are none of the above... that is, they're not quick, and they don't easily connect or disconnect ;)  I shredded my finger and thumbtip pretty fierce trying to jam the damned things on. You can use a pliers, but be careful, because it's easy to bend the connects on the microswitches. It's not a tragedy if you do, since they bend back easily enough, but probably best that you don't.

Dan:
You can use them but your mileage may vary.  If they grip the tabs tight enough to hold on then they should be fine.

Darkmanx:
You crimp them onto the wire that you hook up to the microswitches.  With the quick disconnects on the wire, you can easily disconnect the wire from the switch simply by pulling the connector.

Stripping about 3/8" - 1/4" of insulation should be enough. See my response to your other post re. daisy chaining.

ok, thanks for the help, i really appreciate it. and i realise you guys probly want to smack me, but to daisy chain the common do i just put 2 wires into the round opening or what?

Again, see my response to your other post. Short answer: yes, put two wires in the connect :)

Don't worry about getting smacked. I've said it before and I'll say it again (and I'm sure I speak for most of us): I got an invaluable amount of help from the cab-building community when I was building my cab, and I'm only too happy to give back by helping others.
