When asked to estimate the coil current of a small Omron G5V-2 DPDT relay, most guessed around ... Even the tiny Omron G5V-1 SPDT relay shown in the examples below has a coil current of 30mA at 5V.

When voltage is applied to the coil then the relay switches and now T1 (plus ... In this second application we can use the DPDT switch to choose between 2 different load and have a visual indication ...
