The actuating lever module comprises a module casing, a handle member forming a control lever, a yoke member pivotally supporting the handle for lateral and vertical movement, and detent structure to define handle positions for Left Turn, Off, Right Turn and Emergency switch conditions. The switch module is releasably connected to the lever housing module and includes a casing and rotatable armature member driven responsive movement of the handle to these positions, and includes fixed contacts and movable actuator conductor segments to provide proper current paths for the selective switching functions. The plug module includes a housing having an electrical supply cord connected thereto and a forwardly opening cavity sized to receive the switch module h'ousing nested therein and has forwardly opening blade receiving recesses bounded by electrical contact terminals for electrical connection of the supply cord with the switch module contacts and conductors.
