Decade resistance box with BCD-type rotary switches
For a BCD switch, connect resitors wil values of 1, 2, 4, and 8 ohms (or decade multiples thereof) in series, with a switch in parallel with each resistor - the switches short the unwanted resistor.

Like so:

Beware! this will let you set resistances up to 1500 ohms for this decade.
