MPC500 cursor button tact switch

The down cursor button of my MPC500 doesn't respond as well as the other ones. I have to press it really hard for it to work while the others I can just press lightly to respond. I'm thinking it's the tact switch underneath the cursor button.

Does anyone know if the MPC500 uses the same type of tact switches as the other MPCs?

Because I had the same Question, and measured the tacts.

6mmx6mm Tact switches with 5mm button height

The OP posted one that had incorrect dimensions and the wrong style legs.

i had a similer problem, it was fixed with a quick squirt of contact cleaner

Ok I got the Tact Switches in

(NOT THE ONES EMPTYSEA POSTED THOSE WILL NOT WORK, CHECK MY POST RIGHT AFTER HIS)

and they fit PERFECTLY. They are higher quality as well with a metal top casing instead of the cheap plastic top ones AKAI put in.

I'd imagine these Tact Switches are the same in the MPC1000 as well seeing as how they both use the same plastic buttons to depress these switches.
