In this circuit, the rst relay triggers the second, which then switches on the yellow LED. For controlling power plants or high voltage technology, the isolated connection of additional circuits is important. This allows to implement to convert to different voltage levels for example in a conversion power plant. The switching-cascade is triggered by pushing the button and the yellow LED indicates a current ow in the controlled „third“ circuit.
