TACT SWITCHES AGAIN!!!!!!
I'm just writing to thank all the forum who've posted about the tact switch problem, as I've just replaced dozens of mine.
My MPC 2500 was having problems pretty much from the start with intermittently working buttons, I sort of put up with it knowing that if I pressed this or that button in a certain way then it would work.
Anyway, after my very essential Mode button totally went, I dug in with my soldering iron & seeing that that went well I got about 50 excellent switches for the same price you can get 1 for from one certain MPC parts supplier.
My 2500 feels silky smooth now, this is how them there Numark/AkaiPro should have made them from the start. Using the old switches felt like programming at the end of a big stick by comparison. I've left in a few of the old switches that were working 100% fine & you can still sense the difference.
May I definitely recommend ALPS-SKHHAKA010 as replacement.
I got mine from Farnell, the min order was £20, all the switches were about £8 so I bumped up the order by getting loads of patch cable, which is always useful.

The problem I was having was finding an elegant way of removing the old switches. I tried to get as much solder off with a solder pump, but still had to wedge in a jewellers screwdriver beneath the switches to prize them out while heating from the other side. I'm sure a better suggestion would be appreciated by future tact switch sufferers.
Also, I was finding that there were loose microscopic bits of solder left on the board after I repaired the switch. I think the CPU board is underneath this board, if these bits fell into that then the whole MPC could stop working, so I used a toothbrush to clean off the repaired board's solder debris.
I'm thinking of posting the old switches back to Akai Pro & demanding that whoever was responsible be humiliated infront of the whole MPC production team in a very Japanese stylee for insulting the MPC spirit of Roger Linn. Does anyone know where they live?
Cheers.

Some later posts have additional information and also there is reference to DeoxIt contact spray which may be, for some problems, a good alternative to the soldering option. See how it all pans out.

This tact switch is good for replacing MPC-1000, MPC-2000, and other MPC's red, large tact switches that are used for play, record botton, etc. I know you might notice that the shape is a bit different than the red switches on MPC, but this is compatible. This is nice, Omron brand, 12x12mm flat type switch (the part number is B3W-4000).
