The J-44 Telegraph Key

The J-44 has a small slide switch on top of the base on the right side. The switch functions as a circuit closer, which shorts the two binding posts. Notice the method used to wire the binding posts in the picture at the lower right.

Here you can see the filled cuts used to wire the circuit closing switch to the binding post leads.

The frame on this key does not have "J-37" molded into the left front, but instead has "J-37 E. F. Johnson Co" molded around the back. Very few J-37's have company names on them.
