Enumeration Name	Abbreviation	Meaning	Characteristics	Morse Composition	Examples	Import-only	Comments	ADIF Version	ADIF Status
Morse_Key_Type	SK	Straight Key	a single control which actuates a single switch.	a human makes the dits and dahs and builds characters	Lionel J-38			3.1.7	Proposed
Morse_Key_Type	SS	Sideswiper	a single control which actuates a SPDT (single poll, double throw) switch.	a human makes the dits and dahs and builds characters	W1SFR Green Machine Torsion Bar Cootie			3.1.7	Proposed
Morse_Key_Type	BUG	Mechanical semi-automatic keyer or Bug	a control which actuates a switch as well as a control which actuates a spring and pendulum mechanism which actuates a switch. Both switches are wired in parallel.	a machine makes the dits and a human makes the dahs and builds characters.	Vibroplex Blue Racer Deluxe			3.1.7	Proposed
Morse_Key_Type	FAB	Mechanical fully-automatic keyer or Bug	a control which actuates one of two separate spring and pendulum mechanisms at a time, each of which actuates a switch. Both switches are wired in parallel.	a machine makes the dits and the dahs and a human builds characters.	GHD GN209FA fully-automatic bug			3.1.7	Proposed
Morse_Key_Type	SP	Single Paddle	a single control which actuates two independent switches.	a machine makes the dits and the dahs and a human builds the characters.	American Morse Mini-B			3.1.7	Proposed
Morse_Key_Type	DP	Dual Paddle	two controls which actuate independent switches.	a machine makes the dits and the dahs and a human builds the characters.	Begali Sculpture, VK3IL pressure paddles, M0UKD capacitive touch paddles			3.1.7	Proposed
Morse_Key_Type	CPU	Computer Driven	an electronic device performs the actuation of the switch.	a machine makes the dits and dahs to build the characters.	N1MM+ Logging Software			3.1.7	Proposed
