For sale: a set of parts for beatmania IIDX controllers. Details are as follows: * Buttons (4 white, 3 black) → These were originally from the "RainbowPortable2" controller I used to own. The white buttons are slightly yellowed. * Microswitches (Sanwa Denshi and Chinese manufacturers) → 7 from the aforementioned controller, and 7 (V-10-1A4) that were originally included with Sanwa buttons. I believe the weight of both is 0.98N. * Springs → 4 of the 50g springs sold by Sanwa Denshi, 7 from the buttons, and 6 that were not in the buttons (hardness unknown. I think they are longer and stiffer than the 50g ones). * Microswitch holders (7) → These were attached to the buttons of the aforementioned controller. * Light-emitting diodes (9) → These were the lights attached to the buttons of the aforementioned controller. Some may be dim or not light up at all. Consider them as a bonus. The microswitches worked fine when I was using them, but it was a while ago, so I cannot guarantee their functionality. I am selling them at an affordable price, so please consider purchasing them. DAO Con Dao Con Omron OMROM Rhythm game Ni-dai (IIDX) Pheni One Niji Con (Rainbow Controller) RainbowPortable2
