I was going to replace the tact switches on my mpc and was wondering if the guys that have experience at soldering could give an in-depth step-by-step description of how to do it as efficiently/cleanly as possible. Would be very much appreciated :) .

WHEN I FIRST GOT MY 2000XL THE SLIDER DIDNT WORK ,LIKE A DUMBASS I REPLACED IT MYSELF,HOWEVER DIDNT HAVE A SOLDERING GUN SO I PRYED THE OLD ONE FROM THE BOARD THEN WHEN I INSTALLED THE NEW ONE I JUST POKED THE SPIKE THINGS THROUGH THE BOARD AND BENT THEM BACK TO HOLD SLIDER POST IN PLACE,HORRIBLY WRONG BUT THE FUNNY THING IS IT WORKED !!!!!!!!!!!

using Google before asking questions that are easily answered online is also much appreciated :)

Yeah thanks for that one . . . Just thought someone might want to impart some knowledge on tact switch replacement/soldering on the mpc specifically! Thought it could be a useful resource as this hasn't really been described in detail on the boards before. :)

i'd like to know where to find the tact switches online, what's the part # etc. thanks. just joined to find this stuff out. my down cursor key is out on the mpc2000.

i'd like to add that i am currently in portland, or an any forum member who can meet up/help with the repair would be compensated accordingly.

Again, this is very common parts, many manufactures produce this switch.
Omron B3W-1000, for instance, would fit.

This is the specification:
Tact Switch 6*6mm 5mm Through Hole SPST-NO 50mA
A. It is 6mm by 6mm, and its height is 5mm.
B. SPST-N means Single Pole, Single Throw, Normally Open (most common type)

ALPS and OMRON make tact switches, and they are top brands. The one I got from seller was most likely generic brand, but it was fine, and so cheap. It was $1.00 for 15 switches, I've bought two bags from an eBay seller, shipping was $2.50, so $4.50 for 30 tact switches.


Found this on another part of the forum. I think he pretty much laid it all out there. Most electronics you'll find to be not very special in terms of parts.

I think you should really give it a shot, doing the job yourself. Not even about money. But you would be taking your first step at learning a great skill. It's not difficult at all, altho it can look intimidating at first.

Think of the first time you went to drive a car.

I just push that you give it a shot, because you wont break anything unless your going too fast. Take it nice and slow. At the end of the day it's your call of course :)

Here are the tact switches that I prefer to use on client's MPC2000/XL. It think these switches can be used on other MPCs but definitely not on the MPC3000/LE. The 3000 and Roland MV tact switches have 2 leads instead of 4.
My favorites...
OMRON #B3W-1022 6mmx6mmx5mm sealed tact switch:
