Description:
Rectangular potentiometer with five large stepped dials and four small metal binding posts mounted on a rectangular hard rubber panel. There are two sets of steps marked -1-10 on each dial, so that the dial does not have to be rotated more than 90 degrees either direction to obtain the necessary value. The dials are marked with resistances from x0.0001 to x1. There are also two large switches, one mounted on either side of the two lower dials, and a small, horizontally mounted switch in the lower righthand corner of the panel.
