I recently aquired a Sanwa RDS 8000, but the switch had broken during courier ( ). It Was one of the switches i needed to flick in order for me to start using the Transmitter so i had to make a quick plan.
Got myself a 2 position switch from the local guys at the market and i soldered that on, The new switch was too big to fit properly into the tx hole so i just glued it in enough for me to be able to access it (although carefully).

Mistake i made is that the original switch was 3 position and now i have inserted a 2 position switch. but as this is only temporary, it does the job.

Would be delighted if somebody could tell me where i can buy switches of this size?

Chandni Market Kolkata.

Is that the same as Chandi Chowk?

Yep that's the one and same.
