ButtonWorx™ individual buttons can be used to repair just about any failing rubber keypad.

Most keypads are simple…

In most cases you don’t need to worry too much about the size and shape of things. You can use a 5mm round ButtonWorx™ pad to repair a 3mm square dot keypad or a 7mm triangle shape button. As long as the old keypad can press down on the ButtonWorx™ and the black pad on the BW will short out at least two tracings of the forked contacts you should be good to go.

HOWEVER… not all keypads are alike. Some buttons have LEDs in the middle, possibly other electrical components near by. Maybe solder bumps from a component or jumper wire. There may be a raised white sticker for reflecting light that creates additional button spacer height. Some keypads have a plastic snap dome layer between the rubber and circuit board. Or an additional acrylic plastic part for light reflection.   

With countless potential designs it is hard to provide directions on how to deal with anything and everything you may encounter. 

Keep in mind the basics 

      • 1  The black dot on the old keypad should hit the black dot on the ButtonWorx™ pad when pressed
      • 2 The ButtonWorx™ black dot should never be able to come in contact with any exposed metal or electrical component… other than the forked button contact 
      • 3 You don’t want anything putting pressure on the ButtonWorx™ pad other than the rubber button you are trying to repair. Otherwise the ButtonWorx™ pad could be held down all the time or activate on it’s own without a button press. 
      • 4 You want the ButtonWorx™ pad to be flexible enough to be activated with a light press of the button but not so flexible that simply looking at it the wrong way causes the button to depress.  
    • In general it’s better to use a larger ButtonWorx™ button IF you have the space but at the same time a larger button makes it easier for the material to flex and cause unwanted button presses. 
    • Do not concern yourself with the size and shape of the rubber keypad dot or the circuit board forked contacts. Pay more attention to other things that may be in the way or could put pressure on the flexible part of the ButtonWorx™ pad.
