Contact resistance?		01/01/70 00:00
Correction : Sorry its 10mV to 2500mV		01/01/70 00:00
Voltage or current, pick one		01/01/70 00:00
I can choose Test current as 10mA		01/01/70 00:00
typical constact resistance ?		01/01/70 00:00
yes, but		01/01/70 00:00
No CR when closed?		01/01/70 00:00
If this was possible, you would not need		01/01/70 00:00
