You are buying 1 replacement switch for many many Roland and Boss products like TR 808, Jupiter 6 and 8, Juno models 6 and 60, MC 4 and CSQ series  - many many more....
The original momentary switches are often not working anymore or causing double triggers etc.
I made a small batch of these using US made high quality switches and adapting them for exact replacement of the original Alps switches. Due a slightly more narrow X on top it it is recommended to glue the caps. Price is per piece, please contact me if you need higher quantities. Pictures show a MC 4 overhaul - all switches have been replaced and it works like new now. Will ship WORLDWIDE  in a padded envelope or insured as parcel.

IMPORTANT: If you buy more than one switch you will only pay once for shipping. If you buy them wait for me to send you a revised invoice. If you did already pay, I will refund the money paid too much.
