25g Omron Micro Switch D2MV-01-1C2
The 25g D2MV-01-1C2 Omron switch is popular with players seeking to hit particularly dense patterns. The lighter weight will allow you to maintain stamina easier while hitting those dense patterns. However they do not provide as strong of a feedback compared to other switches due to the light weight and can also be easy to trigger accidentally
Purchased for use on IIDX. Switch provides no real audible or tactile feedback, makes timing difficult if you rely on that. Not quite for me. May be okay with a heavier spring.
