Mother circuit for e.g. controlling and distributing current to daughter circuit, has potentiometer mounted upside down, and variable voltage regulator including three tabs mounted in bridge, where tabs pass above transversal path

摘要

The circuit has a potentiometer (9) mounted upside down, and stopped and fixed by stapling connecting tabs that are carried by insulation mica (13). A variable voltage regulator is welded above the potentiometer, and has three tabs (15) mounted in bridge and passing above a transversal path. A flat button is mounted on cap of the potentiometer, and has a securing rod (28) housed in a central recess (29) of potentiometer case (10).
