uCurrent schematic problem
« on: June 20, 2020, 04:20:23 am »
Hello,
regarding ucurrent design I was confused about the L203011MS02Q switch  mentioned as SW2 in the design. for the off situation 3A to 3B and that's understandable, but during the on station it should connect 2A to 2B which means the net V+ ti +IN and in that case it will disconnect battery from the device which i couldn't understand how??
Is there any mistake i am doing during understanding the schematic? (schematic is down below)

Looking forward for your explanation.
Thanks

If I understand you, you are misreading the switch diagram.  No A terminal is ever connected to any B terminal.  The blue "U" shape shows it connecting adjacent terminals on their respective sides.  For example, in the 'ON' position, 2A to 3A are connected, as well as 2B to 3B.

A 3.5 digit 4.5 digit 5 digit 5.5 digit 6.5 digit 7.5 digit DMM is good enough for most people.
