Type BD 100

Extension switch for 2 earth circuit lines
Battery Ringing System

This instrument consists of a polished walnut base on which are mounted a 3-way lever switch, and a ringer of 100 ohms resistance.
It is intended for use with any of our ordinary battery ringing telephones, and such a combination of switch and telephone can communicate with either of the two extension lines, depending upon the switch being in the left or right hand position.
A signal given by one of the extension lines will ring either the bell on the telephone or that on the extension switch, again depending upon the position of the switch.
The switch should normally be to the left or to the right, and a signal coming from one of the lines will then ring the intermediate station only and not the other extension line.
When the switch is in the central position, the 2 lines can communicate directly with each other.
Height of Backboard: 250 mm.
Width of Backboard: 100 mm.
Weight: 1,8 kg.
Codeword: Batkan.
