Any knob can be used with any rheostat and tap switch model
which has the corresponding shaft diameter. Knobs are fastened to shafts with slotted set screws.
Ohmite coupling kits permit tandem mounting of two rheostat
units. A coupling fastens to the shaft of the back unit; projections
on the coupling engage the recesses in the driving hub of the
front unit.
Each kit consists of a steel “U” frame, a coupling with set
screw, mica washer, allen wrench and instructions.
