Fulton MX-991\U Switch Assembly

[Samuel Culper]

Is there any way to disassemble the switch (shielded) on a Fulton MX-991\U?

I have sprayed Electronics Cleaner into the cracks and crevices as best as I could and that improved my ability to get it to turn On.

With other devices that are not turning on properly or seem to not have full connectivity I have had quite a bit of success in disassembling the switch, plug, or other connecting point, cleaning the metal, wire, or contact points, then applying the thin layer of OxGard grease and reassembling.

The Slide button almost looks the it could be pried apart. Almost! But I am not willing to take that chance on permanently damaging the switch assembly.

Worse Case Scenario; I could try a few more sessions of spraying Electronics Cleaner and see if it will continue to improve connectivity.

Thanks In Advance for any advice or suggestions!

While I can't help with the disassembly of the switch, I would strongly suggest that if the "Electronics Cleaner" you are using is not Caig DeoxIT D100, I would recommend first trying that product specifically, as I believe it is likely the best such product on the market for removal of oxidation from most contact materials and inhibiting its reoccurrence in such applications. It also provides some residual lubricity, which also helps sliding contact surfaces. I use the liquid form (D100L) for exposed contacts which are accessible with a swab, but clearly for your application the aerosol form would be the best at reaching areas not directly accessible. If that's what you're currently using and the results are not proving satisfactory, then your only option may be attempting disassembly of the switch.

Aznsx,
I just ordered; Hosa D100S-2 CAIG DeoxIT 100% Spray Contact Cleaner, 2 oz. for $17.99 that should be here on Monday the 16th. Man!, that stuff is definitely not cheap, but I am willing to trust your advice.

Even though I have ordered the DeoxIT 100% and fully believe that the previous advice is sound and trustworthy, I still would be interested in knowing whether or not the Fulton MX-991\U switch assembly can be disassembled and More Importantly; successfully reassembled if anyone is acquainted with this unit.

Only vid I could find on disassembly. On mine, I used a combination of running hot water while working the switch and then Deoxit as @aznsx suggests. It's much better, but I still have to hit it with the deoxit every once in a while.

Years ago I replaced my flickering Fulton switch with a Brightstar waterproof switch. I believe I drilled out the rivets on the Fulton and used screws to install the new switch, the holes lined up perfectly.

From what I am learning from you three, I believe that I will go with using deoxIT 100% and stop trying to figure out how to take it apart because I would like to leave it in original condition.

Last night I did reapply a few treatments of the CRC QD Electronic Cleaner while manipulating the switch & button followed by blowing it out with Duster compressed air which helped a little bit which leads me to believe that the deoxIT should help quite a bit more.

I will followup with you all when the deoxIT comes in on Monday.

I really appreciate the collective wisdom from you three!
