This switching mechanism is completely enclosed and combines the twin lever for electronic keys with a straight hand key in a pivotless two-paddle design. With this key, CW operators have an instant choice of automatic, semi-automatic, or straight hand keying in one compact unit–by turning the unit on its side, it may be used as a straight key. Although the Permaflex key was designed specifically to key the low currents associated with integrated-circuit keyers, it will handle transmitter currents up to 8 amps.
The contacts are gold-diffused pure silver for protection from corrosion and are adjustable from zero to 0.06 inches. Paddle weight is adjustable from 5 to 50 grams. The paddles are made of rugged fiberglass epoxy with gold-plated copper conductors to ensure a long-term, low resistance, anti-corrosion keyer.
The cabinet is 16-guage chrome-plated steel, with an inner chassis that can be quickly removed for contact gap and tension adjustment. Tho low-mass paddle design and durometer rubber feet permit accurate high-speed keying with a minimum of "walking."
In April, 1971, the company announced a new wider and heavier version of the Permeflex. Included with the new deluxe key is an internal bracket and blank printed circuit board to permit construction of a built-in electronic keyer or monitor.
The pre-punched 1/4" holes on the front panel will accommodate sub-miniature switches and potentiometers.
