Trying to identify the wires in a old apartment building switch to install a smart switch.

Currently only two wires are connected, the red and another one.

I pulled out the other two wires out of the box and tested with touchless electrical tester with light on. No signal. Only signal to the two wires connected to the swithch.

thanks for the help

    Be really careful with those antique cloth covered wires. The cloth insulation can start to fall apart very easily and leave exposed wire when you try and push it back in. Judging by the one wrapped in electrical tape that might have already started to happen though it might have been done to mark one wire as a hot lead.
