The most common way to use the switch box is to evaluate the continuity of a device. You would connect the V+ node to a curve tracer and the V- node to the ground on the same tool. A cable and DUT board are plugged into the switch box output and then the user can toggle switches from the far-left position (grounded pin) to the far-right position (tested pin) one by one for any pin they wish to examine. To float a pin, the switch would be positioned in the middle and the banana jacks are largely unused in this configuration. Overlay templates make it easier for users to find the right switch by replacing the generic switch legend with a customized one.
