A10 Fuel Fill Disable Push/Pull Buttons

Anyone have any part numbers or hints on what to look for for these switches? I'm looking for either a push/pull one or a push on / push off switch which changes height for push on/off. The NKK push on/push off I got don't stay depressed when on.

Yes the switch is MS25089-3G-1 NSN 5930-01-102-3689

930-01-102-3689 ( MS25089-3G-1, MIL-PRF-8805/3, MIL-S-8805/3, 011023689 ) Characteristics Data

Thanks.

Hmmm wonder if this is the right one.

I don't think so it is list as a diffrent type of switch 1 TWO CIRCUIT, DOUBLE BREAK/DOUBLE MAKE, ONE POSITION MOMENTARY SINGLE SWITCH UNIT

Sigh. You know it's going to fun to source a part when searching for the part number results in your post asking about it as the #4 hit on google when searching for the part number.

Online components has no pricing, not listed in Powell or Verical either. MS25089-3G-1 doesn't look to be a manufacturers part number or is it? Do you know if Honeywell makes this and if so what is their part #?

the fun part is searching with out a part number or NSN :smilewink:

Manufacture part numbers

Note: ALL valid part alternates - MS25089-3G-1, MIL-PRF-8805/3, MIL-S-8805/3, 011023689, 5930011023689

No Idea on witch company :thumbup:

Bingo. Otto Switches Part #P1-72632.

Anyone know of any vendors who sell Otto parts? They seem hard to find.

No Otto but have you searched at Digikey? Never seen so many switches.

Gadroc - I got the 4 way DCS switches from Otto before - had to do a minimum order of like 10 IIRC and the company had to order from the factory.

A group buy may be in order.

Call Otto, they will refer you to their regional distributor.

Yea I checked digikey, mouser, newark, allied for push pull switches. They are just not common at all. The ones you linked are all huge electrical cut off emergency stop switches. The closes I can find would be "alternate latching" push buttons, but those are not easy to find either. The ones I've found are not much cheaper than the price list indicates on the otto page for the real thing (assuming I don't get stuck with a huge minimum buy).

push pull switches are commonly built into pots, example.

If the screws are 8/32 (which they look to be) then the knob might be sized smallish enough to work for you.

Plasticoat or rubber dip the knob in black and you might be good to go.

Good catch. There is actually a cheaper version which would work.

To dip the knob. Something more durable than just paint.

Not bad at all.

Here's a thought. Replace the top nut on this car switch with an internal threaded collar that extends up high enough so its top is just above the bottom of the chrome knob when its pulled out. The larger, bottom part of the chrome knob is white which shows when the switch is pulled out, doesn't show when the switch is pushed in. The rest of the switch handle is black.

If the actual A-10 switch has a marker (white) showing when pulled out (Deadman?) this would mimic that feature on the auto switch reasonable well.

:pilotfly:

No White marker on any of my real fill disable switches

That's why I was asking. I thought I saw it in the sim, but didn't know what the real switch has. So, forget the white for the auto switch.

When the switch is pulled out does the switch handle diameter become larger, or is it the same diameter as the smallest diameter of the switch handle?

:pilotfly:

it is a concave shape top and bottom 0.37 in center 0.22 in

Just found this one at Conrad.com:

I know this thread is pretty old but maybe this will help someone else... It is the 5011 switch that Gadroc linked to but from a different supplier

Cole Hersee Push Pull 5011

Otto switches

You might try this supplier: http://www.marineairsupply.com/

I've been able to order Otto switches from them.

Thanks. I usually work from the "no price listed" = "I don't want to pay that price" play book.

I ended up ordering some of the push/pull switches from Pep Boys found in this thread.
