How much

This isn't the one but as an example of price:

Measure it and see what you can come up with.

The 28mm one was just as an example of price, not size... you need to measure yours to see what is fitted.

Here is the schematic diagram: ROTEL RCD-991 SM Service Manual download, schematics, eeprom, repair info for electronics experts. Just wait a minute or so until it says download. At the bottom left corner you will see the in-out signal from the drawer. It is the five pin connector K401 pin 1 and 2, probably from microswitches from the Sony drawer. Pin 4 and 5 is the motor control in and out from IC LB1641. Yes it is limit switches and on page 5 you will see the two leaf switches for in-out on board 51. S151 load out, S152 load in.

With a M signification it would be the whole chassis, sorry

That's good but I really do suspect your problem is most likely microswitch related... which is still an easy fix.
