    Hi, I am new here. Would like to get help for this project.

    In the system is already got the interlock switch which carried signal of 28V.

    Now i would like have a indicator circuit using LED to connect to the interlock switch to detect the status of the interlock switch is on the closed position.

    Is there any simple circuit for it?

    Need help from senior..

    Should not be a big problem. Is the 28V AC or DC? Do you have a schematic? Or, do you know how the 28V signal is in what is in series with the 28V supply and the interlock switch?
