Switch Boxes

Switch Boxes
The switch box was devised to simplify and standardize the interconnection of various test instruments and probe wires. The mechanization of these connections provided improvements in data quality as well as faster operation and less wear on connectors.

The unit on the left was the initial unit developed for power testing. The unit on the right expanded on this basic design to include telephone and cable testing.



High Voltage Sources

High Voltage 11 The combination of these two instruments provided a variable AC/DC, 60Hz source of up to 2000 Volts to conduct testing on power neutral isolators and telephone protectors.
High Voltage 12 The variable AC portion of the power supply.
High Voltage 13 The DC add-on portion.
