Trying to find a couple replacement switches from a CAE RS-10. Reached out to Bob and he doesn't have replacements and seems to be to busy to locate an alternative part. He mentioned it's a Carling 110-BPM-OFF, but cant find that part anywhere. Ordered a 110-PBM-OFF thinking it was a typo in his note, but it's not that part either. Any recommendations, leads, tips?
