Fostex 350 Alps click slide switch 328F 338F 332F 8253002000

These were from a Fostex 350 but may have been used in the 250, Again I have no original information about the manufacturers full part numbers , so if anyone has any data please let me know.

So in the Service manual it says that all of these switches are the same but looking at the top side of the Alps switches they have a different number plus there is a small piece of plastic on the top which is blue or clear.

Maybe its me , or maybe its just mixed lots they supplied but I have a guess that internally they maybe different , as often they used gold contacts or something, so check the sides of yours, it maybe is a tension setting. Its worth getting the right one just in case.
