| Three (3) digit connector switch. Below the relays on top of switch you can a 204C minor switch that is used as the third digit to dial the party. Switch dated 1948 was used in a No 355A office here in Md. Info for switch reads as: COMBINATION CONNECTOR CIRCUIT 8 PARTY TERMINAL PER LINE SEMI-SELECTIVE RINGING. I used these along time ago in my home office. |
