The base of the key is made from stainless steel. The arms and the finger pieces are a lightweight aircraft aluminum alloy. Several other components are gold plated, and the contacts are solid gold.

The ingenious mechanism uses three levers for a clearly defined center position, making it mechanically even more complex than the dual-lever Adventure. The contact spacing can be adjusted with the oval backstop …

The key uses magnets to create the return force which can be adjusted by the golden thumb screw on the bottom. You also see the three precision bearings for the arms.

The key is attached to your radio with a mounting bracket, which lets you swivel the key at an arbitrary angle for maximum comfort in right-handed or left-handed operation. This is the mounting bracket for the Elecraft KX3, but we will also offer (available in January 2013) mounting brackets for the Elecraft KX1 and the Yaesu FT817.

The magnetic desktop base lets you use the key detached from the radio on a desktop or on any metallic surface that the magnets in the bottom of the base can hold on to.

Four strong magnets at the bottom of the base can hold it securely on many metallic surfaces. The combined weight of the key and the base is about half a pound – so, if you have a heavy hand and no metallic surface for the magnets, you can use the mounting holes in the base to secure it in place.

Morse code sudah lama tertulis dalam sejarah, wujud sekitar 176 tahun yang lepas. Mode terawal dalam sejarah penggunaan elektrik sebagai penghantaran mesej melalui wayar dan juga radio tanpa wayar. Operator kod Morse telah banyak menyelamatkan nyawa mereka yang dalam kecemasan. Kapal Titanic sebagai contoh, operator radionya menghantar distress call atau panggilan kecemasan dalam kod Morse. Morse key atau CW key terdapat dalam beberapa jenis, di antaranya adalah:-

1. Straight key – key yang biasa digunakan oleh operator radio tentera, kapal dan juga radio amatur. Key jenis ini sangat mudah, kerana hanya mempunyai 2 sambungan wayar. Bunyi dit atau dah ditentukan oleh ketukan operator. Ketukan pendek akan menjadikan bunyi dit dan ketukan yang panjang menjadikan bunyi dah.
2. Iambic key – iambic key, eletronic key atau automatic keyer biasanya mempunyai 3 sambungan wayar dimana terdapat litar eletronic yang akan menentukan bunyi dit dan dah. Kelajuan ditentukan dalam word per minutes. Kelajuan dan nisbah dit dan dah boleh diubah pada litar eletronik yang mana selalunya terdapat dalam hampir kesemua transceiver moden. Sesuai untuk mereka yang sukakan kod morse dalam kelajuan yang tinggi (high speed telegraphy). Terdapat dalam versi dual paddle atau single lever. Begali menawarkan single lever iambic keyer yang boleh diubah kepada cootie atau sideswiper dengan hanya mengubah satu kedudukan suis.
3. Bug – bug atau semi automatic adalah single lever key yang klasik selalu digunakan oleh operator radio. Mempunyai 2 sambungan wayar, tidak memerlukan litar eletronik sebaliknya key ini mempunyai mekanikal yang akan menentukan bunyi dit. Tetapi, untuk bunyi dah pula operator perlu menghantar secara manual.
4. Cootie – Cootie atau sideswiper adalah satu single lever key, mempunyai 2 contact point dan 2 sambungan wayar. kiri dan kanan contact point adalah sama. Bunyi dit atau dah perlu ditentukan oleh operator.
