Self-closing Patents (Class 178/104)
  • Patent number: 5773769
    Abstract: A twin lever key with horizontal finger pads for code transmission when used with an electronic iambic keyer in Amateur Radio, the index finger and the middle or third finger of the operator resting on the finger pads, whereby signals are generated by pressing the finger pads of either of the two arms singly or in combination thereof, to produce the dot and dash code signals in iambic predetermined code sequences. There is no lateral wrist or hand action as is typical of the common "paddle key" since the hand is held in the horizontal plane and the key is activated by downward vertical motion from the fingers. The key may be used for code practice, normal continuous wave (cw) operating or contesting.
