## Description

Telegraph key is mounted on a solid plastic base.

Review: How can it be anything less than Five Stars? - 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.
Review: Great tool for teaching youth Morse Code - 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.

### ⭐⭐⭐⭐ Good for a Beginner
*by G***H on January 29, 2022*

I have my amateur radio license and had an interest in learning Morse code. My wife, unexpectedly, bought this key for me as a gift. I had to purchase a cable separately to connect the key to my transceiver. I am happy with the key for now. A real good key can cost $200. So, why not try this key before dropping $200? I have been studying the code now for a couple weeks and the key works fine for me. I can make the dits and dahs at approx. 10-12 wpm with this key.
