Hi, I have an Onkyo DX3500 CD player that needs a new micro-switch that detects the position of the CD tray arm that secures the CD in the tray. I have the Service Manual and the part number needed is 25065321, (NMS-1113, Microswitch-Black). It's a specialty item so there isn't really a "substitute" or "alternate" that I've found. I did try and disassemble the bad part but it is so small I can't really work on it even with tweezers. Any help with some possible parts suppliers of NOS Onkyo parts would be great!
