[Elecraft] PTT switch for K3

[Don Wilhelm]

Ted,

Get a round body pushbutton switch, then look around for something to 
contain it which feels comfortable in your hand - the cap from a Sharpie 
marker or the body of a fat ballpoint pen come to mind.  Drill a hole in 
the far end if there is not sufficient opening to pass the wires, and 
put whatever plug on it that fits your transceiver PTT jack.

If the pushbutton does not stay with friction, glue it in with E6000 
cement, or epoxy or whatever works to keep it in place.

If you don't have such materials available, the cost is much smaller 
than buying a commercial pushbutton PTT switch.  The switch and 1/4 inch 
plug can be found at Mouser - choose economy shipping unless you have 
other parts to order.

73,
Don W3FPR
