United ScientificSupplies TGKY01 Telegraph Key

Great packaging and excellent condition great delivery service

Anyone who buys an $8 telegraph key knows something about telegraph keys knows what $8 buys. It's nothing than a thin strip of springy stainless steel you press to close a contact. There's no return spring; the springiness of the metal strip keeps the contacts apart until you tap the knob. The gap is adjusted by bending the metal strip to individual liking and the contact points are durable - you won't live long enough to wear them out. It's a cheap backup key or something to use in the rain besides your antique J-38. You can't rest your fingers on the knob since the arm isn't spring back-tensioned prevent unintentional contact closure. The arm also won't reset as rapidly as it would if spring-returned, but no one can send code fast enough to outrun the action anyway. Last, I drilled a different hole to remount one of the terminal connections. Take a look at the ad photo and you'll see why.

Maybe it's just the inexperienced person here who knew nothing of telegrams and needed one as a prop, but I was hoping I would get a complete working one that could be linked somehow - it's basically what you see in the photo and nothing else. Good and sturdy enough but you'll need to order other parts to get this working. Wish it were more clear before buying :( Still, a good piece that might benefit someone for experiments and all

Me gusta el articulo,

Teaching students about Morse code. This was not great, made very cheap!

I have been using these to teach Morse Code to Scouts working on the Signs, Signals & Codes Merit Badge. To earn this badge, they need to decipher a Morse Code message and then use Morse Code to spell their names and send a message to another Scout. I use a pair of these telegraph keys in troop meetings and classrooms to work with Scouts learning this skill. From their feedback, I can say this is a popular activity and the youth enjoy using them.

I like the telegraph key! I display Railroad artifacts at historical festivals, so this is perfect for kids to get a feel for telegraphy.

Simple for constructing a practice key which the kids and beginners love to use!
