Magnetic Reed Switch

How do I get a magnetic reed switch to send a +ve signal one time and a negative one the next?

I need +ve to turn the power”on” and negative to turn it off. I have one reed switch two trigger magnets.

When open connect terminal 1 to –V via a resistor

connect the side of the resistor tied to the reed to the sense circuit.

Connect terminal 2 to +V with a small resistor.

So when the reed is open, the sense circuit will see –V, and when the reed closes, it will see a positive voltage, determined by the resistor ratio.

Or swap +V and –V if you want it the other way.
