For use in the x0xb0x, you need 23 of these switches.
These switches are unlike the usual tact switch you'd normally see in a x0xb0x. Superior mechanics provide a pleasant, quiet user experience while a completely sealed design ensures an amazing lifetime (10,000,000 presses). It is most likely you'll never have to replace them.
Most other tact switches used in a x0xb0x have an unpleasant feel, are noisy and of inferior quality, causing incorrect data to be sent to the sequencer (double presses). A workaround used to be placing a dust cover inside the x0x, but that only prolongs the lifetime for a couple of years.
From the factory they come with standoff feet to provide optimal positioning on the pcb, but a regular x0xb0x pcb does not have holes for them, so you need to mod them to fit. The standoffs need to be cut. This is easily done with a simple "snap-off blade" utility knife as shown below:
You also need special switch caps. The regular switchcaps used in almost all x0xb0x'es will not fit.
TB-303 & TR-606
Both the Roland TB-303 and TR-606 need 24 of these tact switches. The switches are perfect replacements and need no modification.
The super switch replacement for your 303 (and others). Install these once and you'll never have to replace them again.
- fully sealed design
- avg. lifetime = 10 million presses
- perfect replacement for TB303, TR606, Korg KPR77, ...
