ABSTRACT:
A locking switch includes a shaft that engages one or more electromechanical switches and a knob that is secured to the shaft such that when the knob is rotated, a rotary motion is imparted to the shaft and to the electromechanical switches engaged by the shaft. The locking switch also includes a lock ring having multiple slots and a lock lever that is attached to the knob and that is captured in one of the slots in the lock ring to prevent rotation of the knob.
