me? :) anyway i have here in front of me a desoldered button and although it is possible to pull off the gray rubber, it is impossible to put it back again, you probably need a spacial tool. NO, this is not the proper replacement part, the right Digikey part is: EG4346-ND the E-switch part number is: TL9000F120QG and in the service manula yo ucan find the part number from Yamaha: SKEYAG
