Decade Resistance Box PUBLIC

A tool that might be useful in Bread-boarding.

Four resistors to this circuit, but trimmers can be added for more precision.
Cascade with powers of ten, for more range.

CircuitLab did not have multi position switches to build this circuit.
This is my patch.

Some resistor combinations & switch settings
