Clamp cootie

by OH6DC

This is the cootie key (or sideswiper) I use most often nowadays. It is stable but easily removable, and when I send CW it lets my arm and wrist move freely, instead of resting them on the table.

The key arm and contacts are made of copper clad steel telephone wire. Insulation was left in place at the finger pad end.

Large contact gaps make it easier to send good code.

Here is a video clip, so that you can grasp how the key works:
