Hi, All, Here we have a great SW-20E SWITCH BOX Super high quality. I believe this is used with a handheld data logger to measure stress/strain in civil engineering applications. From manufacturer: (please note for the model 21, I can’t find ref for 20) The SW-21B and SW-21E are 20-channel switching boxes which allow multiple channel inputs in combined use with the TC-32K / TC-31K.
