Hello,

I need some help in finding a circuit for an inverse / reverse switch.
i.e.
there is a circuit with two wires and a bulb. when the wires are joint the ciruit is broken and the bulb stops glowing, instead of the vise-versa.

Thank you!
I'm not an electronic expert. I just like thinking, and making my own projects.

You need either a transistor or a TRIAC depending upon whether the voltage is DC or AC. But both of those require a third wire.

Sounds like a battery, resistor, and bulb in series. Two more wires coming from the bulb terminals. Touch these wires together, it shorts out the bulb, and the bulb goes out.
