 +The Model KR-1 keyer paddle assembly is used in the [[KR20|KR-20]] complete keyer. ​ The actuation paddles are mounted on torque bars which multiply the forces acting on the make-break contacts.
 +To return the paddle after a contact has been made (dit or dah) an ingenious magnetic structure provides the return force. ​ Adjustment knobs on the front panel vary the position of shorting bars which attenuates the return force on the individual paddles. ​ Each paddle can be set to suit individual taste.
 +Contact spacing is adjustable through access holes in the top of the case.
 +In operating, there is a slight "​click"​ which most experienced CW operators like.  It seems to eliminate the "​softness"​ and lack of control often associated with key paddles. ​ Yet, actuation can be made with just a few grams of force.
 +The KR-1 can be used with either squeeze or conventional keying circuits. ​ The entire assembly is housed in a attractive aluminum case.  ​
 +Size:  2" x 4-1/2" x 6"​. ​ Weight: ​ 1 pound.
