Need assistance to hook up a pressure sensor to an ON/OFF sensor

I have zero experience with electronics. I don’t have a voltage meter. For fun, I bought a pressure sensor and an on/off sensor… hoping to connect the two together. I know it’s a long shot. Is it as simple as connecting two wires to the two leads in the sensor? … Or, would I need other parts. If so, any ideas which wires to try first? Would I damage anything by try different pairs of wires?

Heres what it looks like:

So… I’m guessing it’s not as simple as connecting two of the wires from the pressure sensor to the on/off sensors leads?
