Some pic's of my G3KHZ electronic keyer. The single lever has two elements that can move freely. It's got silver-plated contacts and the action is very light.

This keyer was built somewhere around 1974-1976. The knob on the front controls the speed, and through the hole on top of the keyer a potentiometer to adjust the weight (ratio) can be reached.
