The Straight Line Renewable Contact Radio Key

By far the BEST and HANDSOMEST transmitter yet produced. Not only are the contacts renewable, but they are kept in a straight line with perfect surface contact until completely work out, and the lever remains in its original horizontal position.

Fading signals caused by varying resistance of contact points are entirely eliminated.

Its binding posts automatically clamp the wires, making loose connections impossible.
