hello
I recently found this forum while searching for making a custom controller.
Im planning to build a controller that looks like this.

mainly for beatmania style game as you can see.
ive figured out layout for electrical part. but wasnt able to find these recatangle buttons and wondering if anyone has link to dealers that has these on stock.
these are approx. 45~50mm x 30~35mm microswitch recangle buttons.
found some at Wico but heard alot of bad stories from them.. and betson's catalog page wouldnt load up, so couldnt look there.
thanks for your help!
