Marantz PMD-321 Tray Switch

[percival007]

Have a Marantz PMD-321 in need of the Tray Switch.
It's the same Switch as used in all Philips CDM-12......./ VAM12..... etc etc
The Part Number from the Marantz Service Manual is;
4822 276 13222
It looks like there was an alternative Part Number for different Countries (?) This was;
SM000300R
It also lists the (possible) Manufacturer and their Part Number for this Switch. This being;
SINMEI, QAS12299

Does anyone know of any sources for this Switch?

Thanks,

P.
