ABSTRACT:
A control apparatus is provided which is selectively placed in an allowed state in which the apparatus is allowed to be operated and an inhibited state in which the apparatus is inhibited from being operated. The control apparatus includes a first three-position switch and a second three-position switch, each of which has a non-pressed position, an optimum operated position, and an over-pressed position. A controller of the apparatus establishes the inhibited state, irrespective of the operated positions of the three-position switches, when it is determined that both of the first and second three-position switches are pressed down, and establishes the allowed state when it is determined that only one of the first and second three-position switches is pressed down, and is operated to the optimum operated position.
