Abstract
A paddle switch safety button which prevents the paddle switch from being activated prior to the safety button being depressed. A unique multi cross section stem of the safety button cooperates with a U-shaped cutout in the paddle switch lever. The stem interferes with the lever in its extended position and passes in the U-shaped notch in the depressed position to allow the paddle switch lever to be operated.
