My Begali morse key misses some dash

Recently my Begali “Simplex” key starts to miss some dash during transmission, very annoying. I cleaned the moving contacts with isopropyl and triple checked wires and solders, everything ok but the problem was still present.

The bad point was hidden inside the turret that holds the ball contact with the mobile lever.

I removed the contact and the spring and it’s evident the corrosion on the bolt

Maybe the different metal in contact favors the corrosion of this bolt.

Cleaned the dust gently with a small brush and applied a thin layer of vaseline grease.

Now it’s back on air
