Summary

Compact 6 digits resistive decade build with two optional range dials per step 1Ohm-100kOm (1 - 1.11MOhm) or 10Ohm to 1M (10 -10.11MOhm).

all resistors are directly soldered between switch pins 1-2,2-3,3-4...10-11.
other wires goes in series : terminal 1 -- switch1 middle contact, switch1 pin1 -- switch 2 middle contact, switch2 pin1 -- switch 3 middle contact, switch3 pin1 -- switch 4 middle contact, switch4 pin1 -- switch 5 middle contact, switch5 pin1 -- switch 6 middle contact, switch6 pin1 -- terminal 2.
