The present invention relates to conversion between electrical and mechanical energy. In one form, a solenoid assembly is provided which comprises: a housing containing a core member and a coil assembly including at least one coil; a plunger assembly adapted for reciprocal movement within said housing between a first position and a second position; and a driver circuit for energizing said coil assembly to cause said plunger assembly to move at least between said first and second positions and further comprising a linear bearing assembly operatively connecting the plunger assembly with the housing for aligning the reciprocal movement of the plunger assembly with a longitudinal axis of the housing. In a preferred form at least one rod for slidingly engaging with the at least one linear bearing is connected at each end thereof to the housing and disposed parallel to the direction of reciprocal movement of the plunger assembly.
