Rubber Keypad Repair Buttons - What to consider 

You can find them here p1repair.com/universal-button-repair/Universal_Button_Repair-Mix_and_Match.html

Not sure what you mean. There are different sized buttons. If you put a large button repair on a small button then you could short out other buttons or worse (other exposed metal connections). The buttons are never always on because there is a spacer holding the conductive part above the circuit board. The original rubber button has to push down on the repair part to activate it. Unfortunately nothing sticks to rubber keypads for long. I have been working on phone repair for almost 30 years and tried everything. There is no paint, glue or sticker that permanently sticks to silicone rubber. We would get phones back for warranty all the time because of button repair failure. That is why I eventually came up with this.

i was referring to a single button (and not adjacent buttons) and if there is a spacer, that will work as you don't want the conductive surface to always be touching the contacts until the rubber button is touched. i may try this kit when the remote control I just fixed fails again in about a year (I use the conductive paint method on my remotes and it lasts about a year per application).

Most dishwashers I have seen are membrane keypads and not rubber keypads. ButtonWorx will work in some membrane keypad designs that use a forked type contact pad and a solid dot top conductor. If the design uses a design with one leg on the bottom and the other on the top then adding anything between will block one or the other. If you can contact me through my web site with photos I should be able to help more.

I don't have any experience with calculators, but this sounds like a solar calculator maybe with a dead battery?? Have you changed the battery? That might be the only problem. If the keys work OK after 15 min in the sun then I doubt it's a button problem. Much more likely a power problem.

Yes, I did change the battery after it had rust.The problem persists even now. I suspect it is due to mosture or humidity in a damp environment or a short circuit and perhaps capacitance build up in the calculator or any Electromagnetic field whcih is affecting the battery usage. I think the operative environment is bad.I will try to check if it will work properly in a air conditioned room. Something had altered power management in the calculator. The calculator doesnt need solar power from sun on the solar panel . It needs sun on the back. I am not really sure about the technical reason yet. I hope I learn something from this.

An update: The buttons are working after powering on the calculator if I keep the back of the calculator on a metal surface for a few minutes instead of keeping it in sun. If I remove the calculaotor from a metal surface, the buttons stop working after 5-10 minutes.

It's a temporary fix that will not last and can build up between the forked contacts, creating a short. Conductive paint is terrible because it doesn't stick. Guaranteed to flake off and short out buttons, pencil lead has even less reason to stay put.

Yes I've used them on plenty of old devices. Any conductive rubber button can be fixed.

There is a space holding the conductors up off the board.

Ok, I see. Is there a known shelf life for the membranes?

@@robtemple3445 I have scraps of materials from over 10 years ago and they are all fine. Adhesive is as good as day 1

I replied to your email a few days before this message. Did you not receive it?

Update: The button repair kit did not work for me. I tried different size pads but it's worse than ever. I ended up finding a brand new case ($10) for my Key Fob that included a new rubber pad/buttons.

Only the power button working makes it unlikely the buttons are failing. Failing buttons are usually only the heavily used buttons. When all or most buttons stop working (even the ones you rarely use) then it suggests something more serious. I assume the power button is one of the most used buttons so should have failed first, not be the only working button.

I've been repairing button for 30 years. The foil stickers don't last because nothing will stick to rubber. They fall off causing a short circuit or even damaging the device by shifting and shorting out other contacts on the board.

Ben J what about a little aluminum foil glued to the button

@@MaxCaissie Nothing permanently sticks to rubber..... *nothing*

@@p1repair except for rubber cement

@@MaxCaissie I spent over a decade trying every technique and specialty glues you can't buy at any store. Nothing permanently sticks to rubber keypads.

What are you trying to repair?

I've been using these myself for over 10 years and selling them for 5 years. I have several repair facilities re-ordering buttons regularly for many years. These not only work... but they are the only thing that will work for the long run.
