Default Re: Incorrect bell?

Is the electrical part of the bell just the coil, or are there interrupter contacts as you would find on a DC bell?

50 Ohms is far too low a resistance for a normal telephone bell. An REN of 1 corresponds (roughly) to 4k Ohms. Old telephone bells were around 1k.

I am wondering if this bell (given the totally separate connections) was rung by a DC voltage from the exchange.
