[sdiy] Refurbishing of the old Roland rocker switches

[Florian Anwander]

Hello,

I am looking for someone who has experience in overhauling / 
refurbishing the rockerswitches from old Roland string machines, like 
the VP-330, RS-101/202/505 or RS-09.

See http://www.florian-anwander.de/roland_rs505/

In my RS-505 the switches tend to make shakey contact. I tried to open 
them, but it is not possible to get to the switching contacts themselves.
I drilled small holes in the bottom plate and sprayed contact spray 
inside (see last picture), but it did help only a little. I assume, that 
the contact rocker inside is bent flat and the only help might be 
rebending it again.

Did anyone of you ever succeed in disassembling those switches completely?


Regards
Florian
