Description

ABSTRACT:
A sewing machine control box mounted on a non-operative end of a sewing machine frame, and including a partition board which divides the control box into first and second chambers. A transformer which gives off heat in operation is provided in a first chamber, and a printed circuit board which otherwise might be damaged by the heat generated by the transformer is provided in a second chamber. The dividing of the control box into these first and second chambers prevents excessive heat transfer from the transformer to the printed circuit board during operation of the sewing machine.
