Default Re: "Genie" telephone

I've just got a UK Genie (Telephone SR8023, it has the LR button) and it's in bits on the bench. More details when I have figured out more.

The gravity switch has 6 pins. Seems to be one break (when off-hook) contact that is not used and 2 make contacts that are are. The latter would seem to be to connect the telephone circuit to the line and for anti-tinkle as expected.

A word of warning, don't take the gravity switch apart for fun. It's a curious design with spring contacts going over a plastic rocking roller with internal metal contacts. Getting it back together is not at all easy.
