Multiple circuit control
 A control lever extends through a cruciform opening in a control box and inside of the box fixed electrical contacts surround its inner end in an array corresponding to the shape of the cruciform opening. A common electrical contact is connected to the lever. Selective movement of the lever into the guideways provided by the cruciform opening selectively completes electrical contact of the common contact with the fixed electrical contacts to energize a desired electrical circuit. The lever is spring biased so that, when the operating force is removed, the lever returns to a neutral position out of engagement with all fixed contacts. A solenoid is selectively engageable with the lever to restrict movement thereof from the neutral position.
