Telegraph Set
Product Code : JA-PLE-4253
The Telegraph Set (SKU JA-PLE-4253) is a two-unit working model of an electric telegraph, with a Morse key and sounder mounted on teak wood bases. Pressing the key at one station energises the electromagnet of the sounder at the other, so pupils can send and receive Morse code and see an everyday application of electromagnetism. This telegraph set with Morse key is offered with aluminium parts or as an open working model with all-brass parts.
Specifications
Two versions are listed: a Morse sounder and key on teak wood bases, two units, with aluminium parts; and an open working model on teak wood bases, two units, with all-brass parts.
