Re: 8566B Attenuator Service
OH! I remember now after seeing a picture. The insulator on the pin is in fact what OPENS the switch. When the pins moves away. the two spring fingers make contact and THAT is what closes the switch.

Re: 8566B Attenuator Service
This really makes no sense. Let's say it gets the signal to turn 'out' (up). Then the switch to turn 'in' (down) should make contact and the out/up switch should be open. SO at this point, neither
