i have a Yamaha RM1X with some bad buttons, i thought i could try to clean them up with some special spray or likesuchas but they look rather “sealed”, it would probably be better to change all of them, can anybody point me to right direction to get some replacement?
They hace a “gummy” top and a black body and a silent/soft feeling or maybe a “soft/silent/clicky” feeling as they click but with a padded feedback
the picture is quite bad but i only have a web camera at the moment..
couldnt see too well form that photo; so took a rm1x appart which i have here.
they are absolutely standard microswitches (with the exception of the rubber tactile motion) used in everything; cheap as chips.. look up your local big supplier and theyll carry something suitable.
@Artesia: these buttons are 8mm and not 6mm so they wouldn t fit the fooprint, also they have a soft feeling which i would like to keep, if possible and the pins pitch is 4mm (or something like that)
@Stryd: i ve sent a mail to a repair shop in Barcelona, waiting for response..
Yamaha is very good about service manuals - I have manuals for almost every piece of gear I own. Let me know if you can’t get one locally and I’ll order one for you…
good work, a little more thorough than i could be asked with sometimes
unfortunately the actuators are almost always a custom part designed by the company to fit the design & ordered in a silly quantity from a plastic fab.
open the rm1x (but be careful with the flat ribbon cable that goes to the LCD - don’t touch this!!!)
very gently snap off the white and black molded plastic keys
take a blunt pointy object and VERY VERY VERY gently push the rubber membrane of each of the main pattern/note buttons to one side. the point is to be able to get inside the button assembly and scrub it with contact cleaner on the tip of a q-tip or something like that. you may even want to gently scrape the oxidization off the metal contact on the bottom of the button.
carefully, patiently, slowly tuck the rubber membrame of each button back under the bezel of the housing. this takes time and practice. if you rip the rubber membrane, you’re screwed.
Replacing the buttons:
if you’re handy with a soldering iron, then just order new buttons:
anyway i have here in front of me a desoldered button and although it is possible to pull off the gray rubber, it is impossible to put it back again, you probably need a spacial tool.
The digikey part # is:
KSI0M011-ND

NO, this is not the proper replacement part, the right Digikey part is:
EG4346-ND
the E-switch part number is:
TL9000F120QG
and in the service manula yo ucan find the part number from Yamaha:
Makes me wonder if there are some nice actuators for them!
